Reactivity of [N(CH2CH2PPh2)3]CoH toward CS2, SCNPh, OCNPh, and COS

Reaction of (np3)CoH (1) [np3 = tris[2-(diphenylphosphino)ethyl]amine] with CS2, SCNPh, or OCNPh affords (np3)Co(η2-CS2) (2), (np3)Co(η2-SCNPh) (6), and (np3)Co(η2-OCNPh) (8), respectively. In the presence of NaBPh4 1 reacts with CS2 or SCNPh to give [(np3)Co(CS)]BPh4 (3) and [(np3)Co(CNPh)]BPh4 (7), respectively, and with OCNPh or COS to give [(np3)Co(CO)]BPh4 (4). Methylation of 2 by MeSO3F, followed by NaBPh4 addition, leads to [Ph2PCH2CH2N(CH2CH 2PPh2)2Co(CS2Me)]BPh4 (5) through intramolecular attack by a phosphorus atom of np3 on a formed in situ η2-dithiomethyl ester group. On reaction of 5 with NaBH4 the P-CS2Me and C-SMe bonds are cleaved and the thiocarbonyl complex 3 is formed.
