Electrophilicities of symmetrically substituted 1,3-diarylallyl cations

Kinetics of the reactions of nine symmetrically substituted 1,3-diarylallyl cations with different nucleophiles were studied photometrically in dichloromethane, acetonitrile, and DMSO solutions. The second-order rate constants k2 were found to follow the correlation log k2 = sN(N + E). The electrophilicity parameters E of the title cations were derived, using the known values of sN and N of the nucleophilic reaction partners, and compared with the electrophilicities of analogously substituted benzhydrylium ions. Good linear correlations were found between the electrophilicities E and the quantum chemically calculated gas-phase methyl anion affinities of the allyl cations and the σ+ constants of the substituents X.

Phenyl group acceleration of [1,4] carbon-to-oxygen silicon-mediated elimination-rearrangement in β-silyl sulfones. Synthesis of O-silylated cinnamyl alcohols

A very fast [1,4] carbon-to-oxygen silicon migration-rearrangement leading to O-silylated cinnamyl alcohols occurs when the carbanion generated from sulfone 1 is reacted with carbonyl compounds. The mandatory role of the adjacent phenyl ring in this process is demonstrated when compared to the behaviour of the corresponding unsubstituted sulfone 3.

The synthesis of 6,6,6-2H3-2E-hexenal

6,6,6-2H3-2E-Hexenal, leaf-aldehyde, has been synthesised in 45% yield and 99.3% purity by reaction of 3,3,3-2H3-n-propyl magnesium bromide with an ethereal solution of 3-trimethylsiloxy-2-propenal (3) prepared in situ. This new one pot procedure alleviates the need to isolate (3) and should prove useful in the synthesis of other E-α,β-unsaturated aldehydes.
