Reactions of triphenylarsine oxide with aqueous hydrogen fluoride: Crystal structure of bis(triphenylarsine oxide)hydrogen(I) tetrafluoroborate
Autor: James S. McKechnie, H. D. Holden, Gordon S. Harris, David C. Liles, Christopher Glidewell
Publikováno v: Journal of Fluorine Chemistry. 18:143-154
Fluorination of triphenylarsine oxide by aqueous hydrogen fluoride (1–40%) in the absence of glass readily gives triphenylarsine difluoride. When the reaction with dilute (1%) aqueous hydrogen fluoride is carried out in borosilicate glass apparatus

Autor: James R. MacCallum, James S. McKechnie, Colin A. Vincent
Publikováno v: Materials Research Bulletin. 18:743-747
Preliminary results are reported for the electrochemical synthesis of compounds formed by carbon fibre which are analogous to the ‘synthetic metals’ based on graphite and polyacetylene.

Conductometric titration study of the reactions of some trialkylphosphines with bromine, iodine and iodine bromide
Autor: James S. McKechnie, Gordon S. Harris
Publikováno v: Polyhedron. 4:115-120
The reactions of tributyl-, trioctyl-, and tricyclohexyl-phosphine with bromine, iodine and iodine bromide have been studied by conductometric titration in acetonitrile. In general, evidence was obtained for the formation, in solution, of highly cond

Crystal and molecular structure of a 1 : 1 bullvalene–silver tetrafluoroborate complex
Autor: James S. McKechnie, Iain C. Paul
Publikováno v: J. Chem. Soc. B. :1445-1452
The crystal structure of a 1 : 1 bullvalene–silver tetrafluoroborate monohydrate has been determined by X-ray methods on photographic data. The crystals are monoclinic with a= 8·49, b= 14·84, c= 18·74 A, and β= 107°40′. The space group is P2
