Abstract

The palladium/copper(I) iodide cocatalyzed coupling reaction of (Z)‐α‐fluoro‐β‐trifluoromethylstannanes (1) with vinyl iodides (2) has been explored giving substituted α‐fluoro‐β‐trifluoromethyl dienes (3) in 33–95% yields. In studies we have conducted so far, a larger number of the configurations of the products remained unchanged (cases 3a, 3e–h), though in several cases (cases 3b–d) two configurations of the products were obtained. © 2007 Wiley Periodicals, Inc.

The potent antimetabolite, 2-fluoro-L-hi~tidine~ has been synthesized from 2-f luoroimidazole with nonexchangeable 3H labeling in the side chain. 2-Fluoro-4-iodoimidazole was N-tritylated, was subjected to metal-halogen exchange with n-butyllithium, and the carbanion formylated with DMF. The imidazo
