Abstract

Whilst the reaction of cis-[W(≡CR)Br(CO)₂(PPh₃)₂] (R = C₆H₄Me-4) with K[HB(pz)₃] (pz = pyrazol-1-yl) provides [W(≡CR)(CO)₂{HB(pz)₃}], photolysis of the same complex leads to the trans isomer, which with K[HB(pz)₃] provides initially [W(η²-OCCR)(CO)PPh₃){HB(pz)₃}] 2b; subsequent treatment with Cl₂PPh₃ leads to the chloroalkyne complex [W(η²-ClC≡CR)Cl(CO){HB(pz)3}] 4; the crystal structures of 2b and 4 are also reported.
