Stereoselective synthesis of tetrahydropyran-3-ones by rearrangement of oxonium ylides generated from metal carbenoids

The synthesis of tetrahydropyran-3-ones by copper-catalysed reactions of diazo ketone tethered allylic ethers has been explored. Product distribution can be explained by the intermediacy of a free ylide or direct rearrangement of a metal-bound ylide equivalent.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 13395-16-9

[BF4]: A useful synthon for multiple cage boron functionalizations of o -carborane

A simple and efficient method for selective cage B(3) multiple functionalization of o-carborane is described.

The title compounds [MS4Cu4(SCN)2(NC5H5) 6] (M=W (1); M=Mo (2); NC5H5=pyridine) were obtained by the reaction of (NH4)2MS4, CuSCN, KSCN and pyridine. The X-ray analyses of 1 and 2 show that four edges of the tetrahedral MS42- core are coordinated by four copper atoms, giving an MS4Cu4 aggregate of approximate D2h symmetry. The nonlinear optical properties of 1 and 2 were investigated by a Z-scan technique with 7 ns laser pulses of 532 nm.

Synthesis and crystal structure of Me3NHCu2(SCN)3, Me2C=NMe2Cu2(SCN)3, and Me2C=NMe2Ag2(SCN)3. Three-dimensional networks of thiocyanatometallates(I)

Attempts to build up polyanionic networks on the basis of thiocyanatometallates of Cu1 and Ag1 led to the synthesis of three new tris(thiocyanato)dimetallates(I) A[M2(SCN)3] with M = Cu, Ag and A = Me3NH and A = [Me2CNMe2]. The crystal structures show distorted tetrahedral [M(SCN)3(NCS)] and [M(SCN)2(NCS)2] building groups interlinked by SCN bridges. The resulting 3-dimensional frame works accommodate the counter cations in spacious voids. Me3NHCu2(SCN)3 (1) was synthesized by reaction of CuSCN with (CH3)3NHCl in the presence of an excess of KSCN in acetone. 1 crystallizes in the monoclinic space group P21/c with a = 578.4(1), b = 3025.1(5), c = 754.7(3) pm; beta = 112.53; Z = 4. The reaction of CuSCN or AgSCN with (CH3)2NH2Cl and KSCN in acetone resulted in the formation of [Me2CNMe2]Cu2(SCN)3 (2) and [Me2CN-Me2]Ag2(SCN)3 (3). Compound 2 crystallizes in the orthorhombic space group P212121 with a = 720.6(1), b= 1161.5(1), c = 1655.0(2) pm; Z = 4.

Oxidation of white phosphorus by peroxides in aqueous and alcoholic solutions: mechanistic aspects and catalytic studies

The oxidation of white phosphorus by hydrogen peroxide or different organic peroxides (such as tert-butyl hydroperoxide, dibenzoylperoxide, 3-chloroperoxybenzoic acid) has been studied in both aqueous and alcoholic solutions under anaerobic conditions. Depending on the reaction conditions, P(I) (hypophosphorous acid), P(III) [phosphorous acid, mono- and dialkyl (or diaryl) hydrogen phosphonates] and P(V) [phosphoric acid or trialkyl (or triaryl) phosphates] derivatives are produced. The catalytic oxidative P-O coupling of P4 to water, aliphatic alcohols and phenol under mild reaction conditions is accomplished by using copper(I), copper(II) and vanadium(IV) complexes. Catalytic conversion of white phosphorus with complete efficiency and high selectivity for monoalkyl hydrogen phosphonates (>95%) may be achieved using 3-ClC6H4C(O)OOH as oxidant under optimized conditions. An identical radical mechanism is suggested to account for both the stoichiometric and the catalytic oxidative hydroxydation, alkoxydation and phenoxydation of white phosphorus promoted by peroxides in both aqueous biphasic conditions and organic solutions.

Copper-catalyzed cyclopropanation of 1,2,3,4-tetrahydropyridin-2-ones with diazoacetates: A facile and stereoselective synthesis of 3-oxo-2-azabicyclo [4.1.0] heptanes

The reactions of a series of 1,2,3,4-tetrahydropyridin-2-ones (1) with diazoacetates (2) in the presence of copper-bronze catalyst yielded exclusively 3-oxo-2-azabicyclo [4.1.0] heptanes (3 and 4) in excellent yields with high exo-selectivity. Tetrahydropyridin-2-ones (1) with N-alkyl substituents were found to be more reactive than N-aryl substitutents. Among the various copper catalysts studied, copper(II) triflate was found to be the best catalyst while rhodium chloride, ruthenium chloride did not catalyze the reaction. The application of ultrasonic radiation enhanced the reaction rate and allowed the reactions to be conducted at room temperature.
