摘要
The allenylidene complex [Cp* Ru=C=C=CPh2(CO)(PMe'Pr-2)[BAr'(4)] (1) reacts with benzophenoneimine yielding the azaallenyl derivative [Cp*Ru{C(N=CPh2)CH=CPh2}CO)(PMe'Pr-2)][BAr'(4)] (2). The addition of primary or secondary amines to 1 yields vi- nylaminocarbenes, which are better formulated as azoniabutadienyl complexes [Cp*Ru{C(NRR')CH=CPh2}(CO) (PMe'Pr-2)][BAr'(4)] (R=H, R'=CH(2)CdropCH (3), R=H, R'=Me (4), R=R'=Pr (5)). Tertiary phosphines add to the C-alpha atom of 4 the allenylidene chain furnishing allenylphosphonio species [Cp*Ru{C(PR3)C=CPh2}(CO)(PMe'Pr-2)][BAr'(4)] (PR3=PMe3 (6), 4 PMe'Pr-2 (7)). The reaction of 1 with propanethiol afforded the thiocarbene [Cp*Ru{C((SPr)-Pr-n)CH=CPh2}(CO)(PMe'Pr-2)][BAr'(4)] (8), which can be treated as a eta1-thiabutadienyl. (C) 2004 Elsevier B.V.
