Hammett's substitution constant σ for the methylsulphonyl group has been determined, giving σ-meta-CH3SO2 = 0.615 (0.6522) and two values for σ-para-CH3SO2 viz. + 1.15 for the substituted phenol and aniline and + 0.73 for the benzoic acid. This in

Thermal decarboxylation of sodium trichloroacetate in 1,2-dimethoxyethane yields NaCl, CO2, CO, CCl4, perchloroisopropenyl acetate (I) and perchloro-1,2-dimethylenecyclobutane (II). Strong evidence is presented for the intermediate formation of trich

The thermal decarboxylation of alkali trichloroacetates in aprotic solvents in the presence of olefins has been investigated. The isolation of dichlorocyclopropanes in good yields demonstrates the formation of CCl2 as an intermediate. By this method,

L'observation que le groupe carbonyle de la “sulfobenzophenone” (I) est reduit par chauffage avec l'hydrazine nous a amenes a etudier le comportement de quelques autres sulfonylcetones, specialement de celles ou le groupe sulfonyle, soit par prox

N-acetyl-4-methylsulphonyl-2,6-xylidine (I) has been prepared by the convenient method used before, involving thiocyanation of 2,6-xylidine and reduction of the thiocyano group with LiAlH4, followed by methylation and subsequent oxidation of N-acetyl

The rate of the interconversion of 2- and 1-phenylcycloheptatriene upon heating has been measured. These 1-5 shifts - in which the phenyl group is attached to the non-shifting double bond — are somewhat faster than in unsubstituted cycloheptatriene

NMR spectroscopy reveals that the reaction between hepta-1,3,5-triene and potassium amide yields the all-trans heptatrienyl anion, which readily isomerizes to the cycloheptadienyl anion.
