The tetratungstate polyoxoanion-supported organometallic compound 2CH3CN(n-Bu4N)2[{Ir(1,5-COD)}6W4O16]·2CH3CN (2CH3CN1·2CH3CN) is reported, a complex which exhibits an unusual "methyl-first" CH3CN inclusion ("") chemistry. The synthesis of 2CH3CN1·2CH3CN was accomplished by the ...
Alkyl cyanides are prepared in good to excellent yields (average yield 93% )by treatment of alcohols and thiols with 2,4,6-trichloro[1,3,5]triazine/n-Bu4NCN in refluxing acetonitrile. This method is highly selective for conversion of 1° alcohols in the presence of 2° and 3° ones ...

When a quaternary ammonium cation such as [Bu4N]+ is used as a phase-transfer agent for the cyanation reaction, C-N bond cleavage in the cation can occur via two different processes. In the presence of trace water, CN- hydrolysis yields HCN that reacts with Pd(0) to give [(CN)3PdH...
