Abstract: A convenient procedure for the isomerization of α-pinene to β-pinene is described.In thereaction of α-pinene with triethylamminoborine as well as with triethyl-benzylammoniumborane bis-3-pinanylborane was obtained. The latter was isomerized to bis-10-pinanylboranewhich gave β-pinene in the presence of dipentene on heating. The yields of β-pinene were 89.1% and 81.9%,respectively.

Key words: pinene, hydroboration, isomerization
