Mechanism of palladium(II)-copper(II)-mediated demercuration of cycloalkyl and cycloalkylmethyl systems
摘要:
The palladium(II)-copper(II)-mediated demercuration of cycloalkyl- and cycloalkylmethylmercuric chlorides exhibit mechanistic changes as a function of ring size, with elimination-readdition of [HPdX] being important in cyclohexyl systems but direct carbocation formation dominating in cyclooctyl cases.

Low-temperature NMR measurements (H-1, C-13, Hg-199) confirm that organomercuric hydrides (RHgH; R = alkyl, cycloalkyl, phenyl) are characterisable species in solution.
