Treatment
of OsCl2(PPh3)2(CHC(PPh3)CH(OH)-η2-CCH) (1) with PPh3 and Bu4NCl in CH2Cl2 under air gave paramagnetic osmacyclopentene [OsCl2(PPh3)2(CHC(PPh3)CH(OH)C(CH(PPh3)))]Cl (5). Heating the suspension of 5 in CH2Cl2 under a nitrogen atmosphere led
to the formation of η2-allene-coordinated osmacycle
OsCl2(PPh3)(CHC(PPh3)CHCCH(P(C6H4)Ph2)) (6) and chloro-osmabenzene OsCl2(PPh3)2(CHC(PPh3)CHCClCH)
(7) via disproportionation reaction. Oxidative transformation
of 5 under an oxygen atmosphere yielded osmafuran [OsCl(PPh3)2(CHC(PPh3)CHO)(CC(PPh3))]Cl (10). In addtion, complexes 6, 7, and 10 can also undergo ligand substitution
reactions with NaSCN to afford more stable analogues.
