Element-Organic Amine/Imine Compounds, XXIX1). - [(CO)4Re-NR-(Cl)(NR2)-NR], R=SiMe3, a Useful Building Block.The cothermolysis of [(OC)4Re-NR-P(Cl)(NR2)-NR] (1) and RR′N—P=NR′ (2a: R = R′ = SiMe3, 2b: R = SiMe3, R′ = tBu) affords for 2a besides the spirocyclic compound [RN-SiMe2-CH2-(OC)4Re-P-NR′-P(NR)(NHR)-NR′] (3a, b) the tricyclic complex 4. The substitution of 1 with LiCH2SiMe3 (5) gives the five-coordinated d6 rhenium compound [(OC)3Re-NR-P(CH2R)(NR2)-NR] (6). One CO of 6 is substituted by (MeO)3P, with tBuNC further addition occurs. 3b, 4, and 6 have been characterized by X-ray structure analyses.
Notes:
Die Cothermolyse von [(OC)4Re-NR- P(Cl)(NR2-NR] (1) und RR′N—P=NR′ (2a: R = R′ = SiMe3, 2b: R = SiMe3, R′ = tBu) ergibt bei 2a neben dem Spirocyclus [RN- SiMe2-CH2-(OC)4Re-P-NR′-P(NR)(NHR)-NR′] (3a,b) den tricyclischen Komplex 4. Die Substitution von 1 mit LiCH2-SiMe3 (5) führt zum führt zum fünffach koordinierten d6-Rheniumkomplex [(OC)3Re-NR-P(CH2R)(NR2)-NR] (6), der mit (MeO)3P Kohlenmonoxid-Substitution, mit tBuNC zusätzlich Addition ergibt. 3b, 4 und 6 wurden durch Röntgenstrukturanalysen charakterisiert.
