It has been observed that in the hydrolysis of the organophosphorus esters such as paraoxon 1 and ethyl p-nitrophenylmethylphosphonate (2), by aqueous sodium or phosphonium perborate, it is not possible to obtain a complete understanding of the resul

The reactions of menthol with FSO3H–SO2 and neomenthyl chloride with SbF5–SO2ClF follow different routes. The first yields a substituted cyclopentyl cation and the second a substituted cyclohexyl cation. Experiments on substituted cyclohexyl chlo

Methoxydechlorination of 5,6-dichloroazulene in NaOMe–MeOH shows second-order kinetics, apparently proceeding by the SNAr mechanism in which the attack of the nucleophile, and not the loss of chloride ion, is rate-determining. No evidence of a Meis

The two diastereoisomers of N-[(S)-α-phenylethyl]-P-tert-butylphosphonamidothioic chloride (9) give the same mixture of the diastereoisomers of the phosphonamidothioic diamide product (11) with PriNH2 or ButNH2 in dilute solution, i.e. reaction is c

Polyfluorophenyl pentafluorobenzenesulphonates (1) have been synthesized in excellent yields by the reaction of pentafluorobenzenesulphonyl chloride with polyfluorophenoxides. Nucleophilic attack on 1 resulted in the breakage of the S–O bond accomp

Borate ester formation of carbohydrate oximes and related compounds, including acetohydroxamic acid, has been studied using 11B and 13C NMR spectroscopy. It is shown that the oxime hydroxyl is involved in the borate ester formation. The resulting six

The 1H and 13C NMR spectra of erythromycin A in [2H6]-DMSO and buffered D2O have been assigned using a range of one and two dimensional NMR techniques. Assignments have been made for both the major (keto) and minor forms of the drug, and the minor fo

Within the temperature range 303–416 K, the main products of the gas-phase oxidation of trichloroethene by NO2 are nitrosyl chloride, ClNO, and glyoxyloxyl chloride, HC(O)C(O)Cl. Glyoxyloxyl chloride has been isolated by fractional condensation and

Rate constants for solvolyses of 4-methoxy-2,6-dimethylbenzenesulphonyl chloride 3(Z = OMe) and of 4-methyl- and 4-methoxybenzenesulphonyl chlorides 4(Z = Me and OMe) are reported for aqueous binary mixtures with acetone, ethanol and methanol. Some a
