## Abstract The kinetics of the reactions of ground state oxygen atoms with __trans__โ2โbutene, __cis__โ2โbutene, 2โmethylpropene, 2โmethylโ2โbutene, and 2,3โdimethylโ2โbutene was investigated in the temperature range 200 to 370K. In this range, the rate constants are (in units 10^โ11^ cm^3^ s^โ1^)
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
