scheme or table, p. 3822 - 3825 (2011/09/20)
High yielding stereo- and chemoselective Pd-catalyzed cross-couplings in THF at room temperature of alkenyl iodides and bromides with primary and secondary alkyl zinc iodides have been developed with the aid of N-methyimidazole as the key additive.

, p. 365 - 368 (2007/10/02)
Partial reduction of alkynes to (Z)-alkenes is achieved with the low-valent group 5 metal reagents prepared from MtlCl5 (Mtl = Nb or Ta) and zinc in a mixed solvent of DME (or THF) and benzene.
