The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 1111-67-7, Name is Cuprous thiocyanate, belongs to copper-catalyst compound, is a common compound. Computed Properties of CCuNSIn an article, once mentioned the new application about 1111-67-7.
CuI-based coordination polymers with 1,2-ethanedithiol, 3,6-dioxa-1,8-octanedithiol and 3-oxa-1,5-pentanedinitrile as respectively mu-S,S? and mu-N,N? bridging ligands have been prepared by reaction of CuI with the appropriate alkane derivative in acetonitrile. ?2[Cu(HSCH2CH2SH) 2]I (1) contains 44 cationic nets, ? 2[(CuI)2(HSCH2CH2OCH 2CH2OCH2CH2SH)] (2) neutral layers in which stairlike CuI double chains are linked by dithiol spacers. In contrast to these 2D polymers, ?1[CuI(NCCH2CH 2OCH2-CH2CN)] (3) and ? 1[(CuI)4(NCCH2CH2OCH 2CH2CN)2] (4) both contain infinite chains with respectively (CuI)2 rings and distorted (CuI)4 cubes as building units. Solvothermal reaction of CuI with the thiacrown ether 1,4,10-trithia-15-crown-5 (1,4,10TT15C5) in acetonitrile affords the lamellar coordination polymer ?2[(CuI)3(1,4, 10TT15C5)] (7) in which copper atoms of individual CuI double chains are bridged in a mu-S1,S4 manner. The third sulphur atom S10 of the thiacrown ether coordinates a copper(I) atom from a parallel chain to generate a 2D network.
