Abstract: Addition of bis(pinacolato)diboroon [(Me,C,O,)B-B(O,C#e,)] to various allenes was carried out in excellent yields in the presence of Pt(PPh,), at 80 T or Pt(dba)J(c-Hex)g at 50 “c. The addition to internal double bond was predominant for monosubstituted allenes, whereas the terminal diboration products were regioselectively obtained when a sterically bulky phosphine l&and of (c-Hex)? and l,l-disubstituted allenes were used.
