Abstract
The deprotonated aminocarbene complex [Cr(CO)5{C(NH)Ph}]–, when treated successively with CS2 and [Et3O][BF4], affords the thiocarbene complex [Cr(CO)5{C(SEt)Ph}]. Similar reactions with the carbene complex [(OC)5Mn–Mn(CO)4{C(NH2)Ph}] give the nitrite complex [(OC)5Mn–Mn(CO)4(NCPh)]. The carbene anion [Cr(CO)5{C(OEt)CH2}]– gives the vinylcarbene derivatives [Cr(CO)5{C(OEt)CHC(SEt)2}] and [[graphic omitted]Et)SEt}]. Carbon diselenide is less discriminating towards the nature of the anion, and the triselenocarbonate complex [Cr(CO)5{SeC(SeEt)2}] is formed from both carbene anions of chromium.Keywords
