Reactions of the Terminal Rhenium Acetylide Complex Re(η5-C5H5)(NO)(PPh3)(CCH) and Butyllithium; Generation, Alkylation and Stannylation of Lithiocarbide Complexes of the Formula Re(η5-C5H4X)(NO)(PPh3)(CCLi) (X = H, Li)

The title reaction gives, depending upon stoichiometry and conditions, Re(η5-C5H5)(NO)(PPh3)(CCLi) and Re(η5-C5H4Li)(NO)(PPh3)(CLi); the first transition metal-alkali metal carbide complexes which are in turn derivatized by car

Reactions of methyl complexes (η5-C5R4R′)Re(NO)(PPh 3)(CH3) (R/R′ = H/H, H/CH3, CH3/CH3) with HBF4·OEt2, chlorobenzene, and R″C≡CH (R″ = H, CHsu

Synthesis, structure, and reactivity of allene complexes of the chiral rhenium fragment [(η5-C5H5)Re(NO)(PPh3)] +

Reactions of the chlorobenzene complex [(η5-C5H5)Re(NO)(PPh3)(ClC 6H5)]+BF4- and excess (a) allene, (b) methylallene, and (c) 1,1-dimethylallene give the π adducts [(η5-C5H5)Re(NO)(PPh 3)(η2-H2C=C= CRR′)]+BF4- (1a-c) in 90-91% yields. The crystal structure of 1a (monoclinic, P21/n, a = 10.327 (1) A?, b = 10.401 (1) A?, c = 23.919 (2) A?, β = 99.233 (2)°, Z = 4) shows the coordinated =CH2 group to be syn to the PPh3 ligand, with a 23.7° angle between the Re-P bond and the Re-C=C plane. NMR data show that the methyl groups in 1b,c occupy the less hindered positions on the free C=C linkages. Analogous reactions of chiral 1,3-dialkylallenes give mixtures of diastereomeric adducts with modest selectivities. Reaction of 1a and t-BuO-K+ in THF (-80 to +25°C) gives the methylacetylide complex (η5-C5H5)Re(NO)(PPh 3)(C≡CCH3) (3, 92%). A similar reaction of 1a and CH3Li gives the allenyl complex (η5-C5H5)Re(NO)(PPh 3)(CH=C=CH2) (4, 70%), which upon treatment with HBF4·OEt2 gives mainly the propyne complex [(η5-C5H5)Re(NO)(PPh 3)(HC≡CCH3)]+BF4- (5). Reaction of Li+[(η5-C5H5)Re(NO)(PPh 3)]- and HC≡CCH2OTs gives the propargyl complex (η5-C5H5)Re(NO)(PPh3)(CH 2C≡CH), which isomerizes to 4 at 67-80°C. Thus, the conversion of 1a to 3 is proposed to involve 4 and 5 as intermediates.
