Rearrangement of r-5-methyl-c-2-(trimethylsilyl)cyclohexan-t-yl 2,4-dinitrobenzoate in chloroform

Abstract

Isomerisation of the title compound 3 to the ester 4 in deuteriochloroform is believed to occur via rearrangement of an intermediate β-trimethylsilyl substituted carbocation, with subsequent capture by the 2,4-dinitrobenzoate anion.
