M. Hoshi et al., TRANSFER OF ALK-1-ENYL GROUP FROM BORON TO BORON - PREPARATION OF B-[(E)-ALK-1-ENYL]-9-BORABICYCLO[3.3.1]NONANE, Chemical communications, (11), 1998, pp. 1225-1226
Treatment of (E)-alk-1-enyldicyclohexylborane 1 with B-methoxy-9-borab
icyclo[3.3.1]nonane (B-MeO-9-BBN) at 0 degrees C results in transfer o
f alk-1-enyl group from boron to boron to give B-[(E)-alk-1-enyl]-9-BB
N 2 with retention of configuration.
