Copper, organo- compounds preparation

The reaction described is of considerable general utility for the preparation of benzoyloxy derivatives of unsaturated hydrocarbons.2"8 Reactions of 2-butyl perbenzoate with various other classes of compounds in the presence of catalytic amounts of copper ions produce benzoyloxy derivatives. Thus this reaction can also be used to effect one-step oxidation of saturated hydrocarbons,9, 10 esters,6,11 dialkyl and aryl alkyl ethers,12 14 benzylic ethers,11,15 cyclic ethers,13,16 straight-chain and benzylic sulfides,12, 17-19 cyclic sulfides,11,19 amides,11 and certain organo-silicon compounds.20... 

Copper(I) alkanetellurolates and arenetellurolates were prepared from the sodium tellurolates or triphenylstannyl organo tellurium compounds and copper(I) chloride. The copper tellurolates are extremely insoluble, polymeric red-brown solids. 

Similarly prepared using organo triphenylstannyl tellurium compounds as starting materials were the following copper tellurolates ... 

Organosilicon compounds were prepared by the metathesis reaction of organo-zinc compounds with silicon tetrachoride as shown in eq. (2.11) in 1861. However, in 1941, Rochow [32—34] developed a direct reaction method with a copper catalyst, and a great amount of organosilicon compounds were easily prepared by this reaction method. Organosilicon compounds have become rapidly more numerous and 600 00 tons or more were produced in 1994. Thus they became the organometallic compound produced in the largest amount [34a,34b]. 

Methods for the preparation of air stable trimethylsilyl substituted trivinylboranes and 9-halo-9-borafluorenes (which are readily converted into methoxy, methylthio and diethyl amino derivatives) have been published. The ability of various cuprates to transfer organo groups to 9-BBN has been investigated and the reactions of aromatic organo copper compounds with organoboranes probed. ... 

The reaction of benzothiazole with / -iodonitrobenzene at 200 °C in the presence of cuprous oxide gives a 72% yield of 2-(p-nitrophenyl)benzothiazole. 2-(/>-Methoxyphenyl)thiazole and 2,2 -bibenzothiazolyl may be prepared similarly. Whilst suggesting the organo-copper compound (1 R = Cu) as a probable intermediate, the authors have also considered the possibility of a copper-complexed carbene as an intermediate.
