Metal and temperature effects on thio-Wittig reactions have been studied. Stabilized phosphorus ylides, such as carbomethoxymethylenetriphenylphosphorane, reacted with sulfur to afford dimethyl maleate and dimethyl fumarate in a 1 : 4 ratio. As in the case of conventional Wittig reactions with semis
A friction model for cis-trans isomerization is proposed. The friction is a linear combination of two limits, reflecting relative time scales of system and solvent motiohs. The resulting extended Kramers equation fits MD results exactly and is applicable to real isomerizing systems as well.
