Recent advances in Markov chain Monte Carlo (MCMC) extend the scope of Bayesian inference to models for which the likelihood function is intractable. Although these developments allow us to estimate model parameters, other basic problems such as esti

Attempts to demethylate and decarboxylate various bromomethoxybenzoic acids in one stage led either in incomplete reaction with some acids or to rearrangement and debromination, depending on the catalysts used; a two-stage reaction, using hydriodic a

An attempt has been made to determine the structure of novolak resins by controlled degradation involving the steps: bromination, methylation of the phenolic groups, oxidation to polyketones, cleavage of the polyketones to bromoacids and bromoanisole

The six two-ring novolaks theoretically obtainable from m-cresol and formaldehyde have been synthesized and the three dinuclear novolaks involving one molecule each of m-cresol and p-cresol have been prepared. The uniformity of each product is confir

Olefins of various structures have been oxidized with oxygen at 85–125°, generally in the presence of mild alkali and a catalyst, and the products examined. These products were complex mixtures and appeared to have been derived from attack at seve

Treatment of the bicycloalkyl-2,2′-diones obtained from oxidation by nickel peroxide of cyclopentanone, cyclohexanone, 4-methylcyclohexanone, and cycloheptanone with hydrogen peroxide afforded the corresponding symmetrical dihydroxy-peroxides (3,6-

Re-examination of the isomerisation of 1,1′-epoxybicyclohexyl-2-one into spiro-diketones has confirmed that reaction with antimony pentachloride in sulphur dioxide affords cycloheptanespirocyclohexane-2,7-dione, whereas thermal rearrangement gives
