1. The photochemical reaction of p-benzoquinone with i-C3H7OH in CCl4 proceeds along two different paths, the initial act being the detachment of an H atom from theα- C atom of the alcohol by the triplet quinone, in the one (a), and acceptance of an

The reaction of substituted methyl 1-adamantyl ketones with an equimolar amount of 5-phenyl-2,3-dihydrofuran-2,3-dione under the conditions of the thermal decarbonylation of the latter leads to the corresponding 2-methyl-2-adamantyl-6-pheny1-1,3-diox

Aldehyde (δCH) and enolic (δOH) proton chemical shifts, the corresponding spin–spin coupling constants (JCH,OH) and the 13C chemical shifts (δC) have been measured for three cyclic β-ketoaldehydes as a function of temperature. A tautomeric equi

For symmetric (X = Y) B-diketones, up to 130~ PMR spectra are observed which are characteristic of a chelate ring with the C2o symmetry [2, 3]. This indicates either rapid migration of the enol proton in a double well potential, or in the existence o
