(Matrix presented) The time-resolved infrared (TRIR) spectra of chlorophenylcarbene (CPC) and fluorophenylcarbene (FPC) were recorded in heptane at ambient temperature. The C-C and C-F vibrational frequencies involving the carbene carbon were obtained in heptane, benzene, and acetonitrile and in heptane containing 0. 1M tetrahydrofuran or benzene. It is concluded that carbene-solvent interactions of CPC and FPC are quite weak.

The absolute rate constants for the cycloaddition reactions of three arylhalocarbenes to two alkenes have been measured as a function of pressure in the range 0.1 to 203 MPa.In all cases the observed rate constants were found to increase with increasing pressure.The magnitude of the derived activation volumes falls in the range of -10 to -18 cm3/mol and does not depend on solvent.The results rule out a late, two-bond transition state and a bipolar single-bond transition state but are consistent with the reversible formation of a carbene-alkene complex or an early one- or two-bond transition state.

The absolute rate constants determined for the additions of FCPh, ClCPh, and BrCPh to Me2C=CMe2, Me2C=CHMe, trans-MeCH=CHEt, and n-BuCH=CH2, appear to follow a reactivity/selectivity pattern of the "normal" (inverse) type.
