Abstract: The reaction of thiophenol with borane in tetrahydrofuran produces monomeric phenylthioborane. The structure of phenylthioborane was deduced from infrared and boron- 1 1 magnetic resonance spectral data and molecular weight measurements. In contrast, benzyl mercaptan reacts with borane in tetrahydrofuran to produce a polymeric benzylthioborane. Aryl-and alkylthioboranes have been found to be effective ether ...
