A procedure for high level tritium labelling at the C2-H position of adenosine 5'-triphosphate ([2- 3 H]-ATP, 1), based on the tritiodehalogenation reaction of 2-bromoadenosine 5'-triphosphate (2) has been elaborated. This precursor was prepared in a

The synthesis of [2-3H]ATP with specific activity high enough to use for 3H NMR spectroscopy at micromolar concentrations was accomplished by tritiodehalogenation of 2-Br-ATP. ATP with greater than 80% substitution at the 2-position and negligible tr

Enthalpies of solution of D-α-methyl-α-phenylacetophenone in a series of dimethyl sulphoxide–water mixtures have been measured. Taken in conjunction with the enthalpies of transfer of the hydroxide ion from a 27.8 mol% dimethyl sulphoxide–water

3 H N.m.r. spectroscopy is used to determine directly the regio- and stereo-specificity of the labelling in penicillic acid, biosynthesised by Penicillium cyclopium from [3H]acetate, from [2-3H]malonate, and from [3,5-3H]orsellinic acid. In particula

Rate constants for the base-catalysed detritiation of diethyl malonate have been determined in aqueous solution. Various indicators of transition state structure, such as primary hydrogen isotope effects, Bronsted β exponent, rates of ion recombinat

In a first application of 3H n.m.r. spectroscopy to a biosynthetic investigation, namely the incorporation of [3H]acetate by Penicillium cyclopium into penicillic acid (I), the stereospecificity of labelling of the vinyl methylene group is directly d
