Y. Yamamoto et al., A regio- and stereoselective platinum(0)-catalyzed hydroboration of allenes controlled by phosphine ligands, CHEM LETT, (10), 1999, pp. 1069-1070
The hydroboration of terminal allenes with pinacolborane was carried out at
50 degrees C in the presence of a Pt(dba)(2)/2PR(3) catalyst The formation
of one of three possible monohydroboration products was regioselectively s
ynthesized by choosing an appropriate phosphine ligand.
