Abstract

The intermediate formed from tetrachloromethane-triphenylphosphine and neopentyl alcohol decomposes bimolecularly in acetonitrile and not unimolecularly as in CDC13. This kinetic order is not consistent with a pericyclic pathway but is consistent with an ion-pair mechanism. Consistent with the ion-pair mechanism in acetonitrile is the incorporation of external nucleophiles in the neopentyl skeleton by addition of added nucleophiles to the ...
