The role of individual organic acids in relation to the excessive acidity exhibited by Asian cocoa liquors has been investigated. Volatile fatty acids (other than acetic) did not affect significantly either acidity scores or liquor pH. Variations in

The electrochemical oxidation of 3-amino-4,5-dihydro-1-phenylpyrazole in acetonitrile has been examined. One reversible oxidation wave was observed between the potentials –0.6 and 0.9 V versus s.c.e. Controlled potential electrolysis indicated the

The electrochemical oxidation of 1-phenylpyrazolidin-3-one in acetonitrile has been studied. Two oxidation waves were observed using cyclic voltammetry and these were found to be due to the oxidation of the protonated and neutral compound. Controlled

Phenyl radicals derived from N-nitrosoacetanilide, dibenzoyl peroxide, or di-t-butyl peroxide–triphenylarsine react with dimethyl acetylenedicarboxylate (DMAD) to give tetramethylnaphthalene-1,2,3,4-tetracarboxylates, the maximum yield being 0·5 m

Dialkyl azodiformates (RO2C·NN·CO2R; R = Me, Et, or But) do not undergo annelation reactions with phenyl radicals from benzoyl peroxide, to give tetrahydrobenzotetrazines. Instead they give good yields (up to 69%) of the novel, very stable tetra-al

An easily effected aromatic annelation is described, involving reaction of an aryl radical with two molecules of dimethyl acetylenedicarboxylate to give 1,2,3,4-tetramethoxycarbonylnaphthalenes.

Reaction of aniline with pentyl nitrite and acetic anhydride in benzene, or other solvents, gives benzyne in up to 32% yield as measured by trapping with anthracene, and tetraphenylcyclopentadienone and its 2,5-di-p-tolyl analogue. The role of the an
