, p. 767 - 776 (2007/10/02)
The E/Z stereochemistry of vinyl derivatives (sulphides, enamines, ethers) is investigated using 13C NMR spectroscopy.Calculation of substituent increments for these compounds and alkenes is presented.
REGIOCHEMICAL CONTROL IN THE 1,2-CARBONYL TRANSPOSITION OF α,α'-DIMETHYLENE SYSTEMS THROUGH REGIOSELECTIVE SULFENYLATION OF TOSYLHYDRAZONE DIANIONS

The regiochemical outcomes are described in the 1,2-carbonyl shift of α,α'-dimethylene systems which relies upon the regioselective sulfenylation of tosylhydrazone dianions leading to the enol thioethers of transposed ketones.Notably, a high regiospecificity was obtained with β-methyl- and β,β-dimethylcyclohexanone without any attempts to separate the stereoisomers of the hydrazones.
