H-1 and C-13 NMR Spectra of the Carbanions Produced from Phenylpropene Derivatives
نویسندگان
چکیده
l,l-Diphenyl-2-methyl-l-propene produces an equimolar mixture of two carbanions in contact with excess potassium-sodium alloy in tetrahydrofuran. The carbanions can be interpreted as the products of disproportionation reaction between two radical anions produced by one-electron reduction of the phenylpropene with alkali metal.

The 1H and natural-abundance 13C-NMR spectra of 1-thiacyclooctan-3-one (1) have been measured from 25 to -100°C. Coalescence is observed in the 1H-NMR spectra of (1) at about -80°C, and attributed to ring inversion in a boat-chair conformation, which is the predominant conformation of (1). The free energy of activation (DG¹</s...
