Synthesis and chemistry of chiral rhenium acyls (η-C5H5)Re(NO)(PPh3)(COR)

Rhenium acyls (η-C5H5)Re(NO)(PPh3)(COR) (R = CH3 (2), CH2CH3 (3), CH2-n-C8H17 (4), C6H5 (5), CH2C6H5 (6), CH2CH2C6H5 (7), CH=CH2 (8), CH2CH=CH2 (9)) are prepared in high yield by RMgX attack upon (η-C5H5)Re(NO)(PPh3)(COOCH3) (1). Acyl (η-C5H5)Re(NO)(PPh3)(COC≡CCH 3) (10) is prepared by LiC≡CCH3 attack upon [(η-C5H5)Re(NO)(PPh3)(CO)] +BF4-. Acyls 2, 5, and 7 are also prepared in optically active form from optically active 1. These compounds are characterized by IR, 1H NMR, 13C NMR, and (when optically active) ORD and CD. They are shown to undergo high-yield (1) BH3 reduction ((-)-(R)-2, 4, (+)-(R)-5, 7) to the corresponding alkyls (η-C5H5)Re(NO)(PPh3)(CH2R), (2) methylation with CH3SO3F/NH4+ PF6- (2, 5) to methoxycarbenes [(η-C5H5)Re(NO)(PPh3)(=C(OCH 3)R)]+ PF6-, and (3) protonation with CF3SO3H (2, 3) to hydroxycarbenes [(η-C5H5)Re(NO)(PPh3)(=C(OH)R)] +CF3SO3-. Structures for the preferred conformers of 2-10 and their methylation and protonation products are suggested.
