- 中文摘要: Hydroboration of styrene with generated diborane followed by protonolysis withacetic acid gave ethylbenzene.as the main product at a yield of 54.6%. No acylatedethylbenzenes were found in the by-products. It is obvious that direct acylationdoes not tale place during the hydroboration and protonolysis. Since the organo-borane produced in the hydroboration of styrene is B- but not a-phenylethyl boranedue to steric hindrance, no intramolecular acylation through the rearrangement ofthe organobnrane acetate could be expected. This experiment has provided evidencefor the intramolecular acylation mechanism proposed for the acylation of acenaph-thenyl borane in author's previous work.
