Dependence of activation parameters for phenylchlorocarbene-alkene additions on alkane solvent chain length

Activation energies, enthalpies, and entropies for the addition of phenylchlorocarbene to tetramethylethylene significantly decrease as the reaction solvent lengthens from n-pentane to n-octane to n-decane; additional decreases are minimal in n-pentadecan

Activation Parameters for the Reaction of Phenylchloro Carbene with Pyridine, Tri-n-butyltin Hydride, and Triethylsilane; Evidence Against the Need to Invoke Reversibly Formed Complexes in the Reaction of This Carbene with Olefins

The activation energies for reaction of phenylchloro carbene with pyridine, tri-n-butyl-tin hydride and triethylsilane are reported.The data argues against reversibly formed complexes in the reaction of this carbene with olefins.

Complexes and Negative Activation Energies in Arylhalocarbene/Alkene Additions: Activation Parameter Dependence on Alkane Solvent Chain Length

Activation parameters for the additions of PhCCl, F5-PhCCl, and 3,5-dinitro-PhCCl to tetramethylethylene, cyclohexene, and 1-hexene have been determined in decane. With the exception of two carbene/alkene combinations, Arrhenius correlations of

Application of alkali metal hydroxides for the preparation of gem-chlorophenylcyclopropanes

gem-Chlorophenylcyclopropanes 3 are conveniently prepared by reaction of benzal chloride (1) with alkenes 2, carried out either in the presence of solid potassium hydroxide and 18-crown-6 as a catalyst or cesium hydroxide monohydrate, without solvent. Cop

Cycloaddition of Arylchlorocarbenes using Ultrasound

An alternative method for the generation of arylchlorocarbenes using ultrasound is described.

Chlorofluorocarbene from Reaction of Fluorotrichloromethane with Reduced Titanium. Synthesis of 1-Chloro-1-fluorocyclopropanes

Generation of chlorofluorocarbene by reaction of CFCl3 with reduced titanium at O deg C, in the presence of various alkenes, produces 1-chloro-1-fluorocyclopropanes in good yield.Evidence from the syn/anti product ratios, including generation of chloroflu

Volumes of Activation for the Cycloaddition Reactions of Phenylhalocarbenes to Alkenes

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.

ABSOLUTE RATE CONSTANTS FOR THE ADDITIONS OF HALOPHENYLCARBENES TO ALKENES; A REACTIVITY-SELECTIVITY RELATION

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.

HAMMETT ANALYSIS OF ABSOLUTE CARBENE ADDITION RATE CONSTANTS

Absolute rate constants were determined for the additions of 5 p-X-substituted ArCCl (X=CF3, Cl, H, CH3, CH3O) to tetramethylethylene, trimethylethylene, trans-pentene, and 1-hexene; good Hammett correlations were obtained with ρ= +1.4 - 1.6.
