Treatment of olefins with a mixture of iodine and mercury(II) thiocyanate in benzene or diethyl ether gives vic-iodo(isothiocyanato)alkanes and vic-iodo(thiocyanato)alkanes in a high yield, the former being predominant. Similar results were obtained by using silver(I) and thallium(I) thiocyanates, though both the yield and the selectivity are slightly lower. By use of potassium thiocyanate and copper(I) isothiocyanate in place of mercury(II) thiocyanate, beta -iodo thiocyanates were mainly formed. A reaction scheme involving initial formation of an iodonium ion from olefin and ISCN (formed in situ) and a subsequent attack of complex anion I(SCN)//2** minus has been proposed to account for this predominant formation of beta -iodo isothiocyanates.

Electric Literature of 13395-16-9, As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. In an article, once mentioned the application of Electric Literature of 13395-16-9, Name is Bis(acetylacetone)copper,molecular formula is C10H16CuO4, is a conventional compound. this article was the specific content is as follows.

Nanocrystals of multicomponent chalcogenides, such as Cu 2ZnSnS4 (CZTS), are potential building blocks for low-cost thin-film photovoltaics (PVs). CZTS PV devices with modest efficiencies have been realized through postdeposition annealing at high temperatures in Se vapor. However, little is known about the precise role of Se in the CZTS system. We report the direct solution-phase synthesis and characterization of Cu 2ZnSn(S1-xSex)4 nanocrystals (0 ? x ? 1) with the aim of probing the role of Se incorporation into CZTS. Our results indicate that increasing the amount of Se increases the lattice parameters, slightly decreases the band gap, and most importantly increases the electrical conductivity of the nanocrystals without a need for annealing.

A process for preparing a 3- or 4-aminobenzocyclobutene comprises aminating a 3- or 4-halo- or sulfonyloxybenzocyclobutene reactant with an aminating agent by heating at a temperature from about 80 C. to a temperature at which dimerization or oligomerization of a benzocyclobutene reactant or product is a significant side reaction, in the presence of a metal-containing catalyst, for a time sufficient to aminate the halo- or sulfonyloxybenzocyclobutene reactant. In another aspect, this invention relates to a process for making a 3- or 4-phthalimido- or maleimidobenzocyclobutene, comprising reacting a 3- or 4-halobenzocyclobutene reactant with a phthalimide or maleimide compound in the presence of a metal-containing catalyst. The resulting phthalimido- or maleimidobenzocyclobutene can be hydrolyzed to a 3- or 4-aminobenzocyclobutene.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Synthetic Route of 1317-39-1, you can also check out more blogs aboutSynthetic Route of 1317-39-1

The imminent ban of environmentally harmful tributyltin (TBT)-based paint products has been the cause of a major change in the antifouling paint industry. In the past decade, several tin-free products have reached the commercial market, and claimed their effectiveness as regards the prevention of marine biofouling on ships in an environmentally friendly manner. The main objective of this review is to describe these products in as much detail as possible based on the knowledge available in the open literature. This knowledge has been supplemented by means of performance data provided, upon request, by some of the paint-producing companies. An exhaustive review of the historical development of antifouling systems and a detailed characterisation of sea water are also included. The need for studies on the behaviour of chemically active paints under different sea water conditions is emphasised. In addition, the most common booster biocides used to replace TBT-containing compounds are listed and described. It must be stressed that there is still a lack of knowledge of their potential environmental side effects. The current interest in providing innovative antifouling technologies based on an improved understanding of the biological principles of the biofouling process is also considered in this review. From the analysis of the factors affecting the biofouling process, the interference with the settlement and attachment mechanisms is the most promising environmentally benign option. This can be accomplished in two main ways: imitation of the natural antifouling processes and modification of the characteristics of the substrate. The former mostly focuses on the study of the large amount of secondary metabolites secreted by many different marine organisms to control the fouling on their surfaces. The many obstacles that need to be overcome for the success of this research are analysed. The potential development of broad-spectrum efficient coatings based on natural antifoulants is far from commercialisation. However, exploitation of a weakening of biofouling adhesion by means of the non-stick and fouling-release concepts is at a rather advanced stage of development. The main advantages and drawbacks of these systems are presented along with a brief introduction to their scientific basis. Finally, other alternatives, which may eventually give rise to an efficient and environmentally benign antifouling system, are outlined.
