The relative rates of hydrogen abstraction from 1-phenylalkanes and a,w-diphenylalkanes using N-bromosuccinimide and bromotrichloromethane were determined at 70°C. In both cases the reactions were photoinitiated. Only benzylic bromination was observed. The 1-phenylalkanes reacted with both reagents to give rates largely independent of substrate. Similarly, the rate of the reaction between...
Sequential alkylation of Hagemann's ester with methyl and
methallyl halides has been studied. Treatment of Hagemann's ester
with methyl iodide and sodium ethoxide gave a mixture of 21 and 25
in a ratio of 4:1. Alkylation of 21 with methallyl chloride and potassium
t-butoxide afforded a mixture of 37 and...
