Practical guidance for obtaining optimum cis-selectivities in Wittig reactions with triphenylphosphonio-alkanides

The crucial role is played by the base, the solvent, and the temp. in detg. the stereochem. outcome of salt-free olefination reactions. Under optimized conditions unprecedented cis-selectivities are obsd. [on SciFinder (R)]
