Alkyl groups in trialkylboranes were successfully transferred to carbonylcompounds in the presence of the platinum cathode and copper anode by electrochemical method. The new, mild electrochemical alkyl transfer reaction produced various substituted alcohols in good yields.

which on ammonium acetate-induced cyclisation afford 4-arylnicotinaldehydes in good yields. Tertiary alcohols derived from aliphatic or alicyclic ketones by the addition of methyl Grignard are converted into substituted pyridines and naphthyridines by the action of Vilsmeier's reagent in N,N-dimethylformamide followed by nucleophile-assisted cyclisation in the presence of ammonium acetate.
The substituent effect on the solvolysis of α,α-diisopropylbenzyl chlorides can be described in terms of σ+ value. No significant steric loss of resonance was observed by introducing two bulky isopropyl groups into benzylic reaction center.
