[WBr2 (CO)4] reacts with cycloocta-1,5-diene, cyclooctatetraene and norbornadiene (LL) to give complexes [WBr2(CO)LL]2 (I) which react with Lewis bases (L) &L CNBut, PMe2Ph, (POMe)3&} to give coordinatively unsaturated diene complexes [WBr2CO(LL)L] (II) and coordinatively saturated derivatives [WBr2(CO)(LL)L2] (III) (LL NBD) and [WBr2(CO)2L3] (IV). Two isomeric forms of the diene complexesII exist
