Abstract
Experimental evidence for the production of propene ion in the gas phase re action of ionized dichlorocarbene with acetone is provided owing to the use of an original hybrid tandem mass spectrometer of sector-quadrupole sector configuration. Ionized dimethylcarbene is a transient intermediate that ra pidly rearranges into its more stable isomer. Relative stabilities between both isomeric forms in different electronic states are evaluated using B3LY P/6-311++G(d,p) computations. (C) 2001 Elsevier Science Ltd. All rights res erved.
