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.
