KINETICS AND SPECTROSCOPY OF YLIDS FROM REACTION OF p-SUBSTITUTED PHENYLCHLOROCARBENES WITH ACETONE

Article abstract of DOI:10.1016/0040-4039(88)85178-5

Laser flash photolysis of p-CF3 and p-Cl-phenylchloro diazirines produces the corresponding carbenes which react with acetone to produce easily detected ylids.The absolute rate constants of reaction of these carbenes with acetone, and the rate constants of reaction of the ylids with diethylfumarate have been determined.No reaction was found between these carbenes and simple esters or ethylene carbonate.
