Abstract

not only methylation, but diazomethane homologation as well. 5 The nmr spectrum of the alcohol obtained by borohydride reduction confirmed this assignment. It showed a one- proton multiplet at 6 4.62, and a two-proton multiplet at 6 2.87 as well as an envelope (three protons) between 6 1.2 and 2.16. The low-field proton must be that on the carbinol carbon, those at 6 2.87 the benzyl protons, and the high-field envelope must be the methylene and ...
