Abstract Cyclopropanecarboxylic acid chlorides5a-d react with tris(trimethylsilyl)phosphane6 in benzene at −2 °C to form cyclopropylcarbonyl-bis(trimethylsilyl)phosphanes7. These products undergo silylic rearrangement at 25 °C to yield phosphaalkenes8. Compounds 8a,b,d are formed as mixtures ofZ- andE-isomers where the latter predominate. In the case of8c, theZ-isomer is formed exclusively.
