The reaction of 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2a]pyrimidinyl potassium, [hpp]−K+ (1), with dimethyldichlorosilane, diphenyldichlorosilane or cyclotetramethylenedichlorosilane (1,1-dichloro silolane) in THF resulted in the formation of the in

Bis-(1,2-(RMe2SiO)2)ZrCl2 complexes with R = Me-(5a), iPr-(5b) and tBu-(5c) have been synthesised in good yields and characterised. Compounds 5a–c are the first synthesised examples of multi-siloxy-substituted cyclopentadienyl metallocenes. The sil

Oxidation of specifically deuterated 3,3-dimethyl-1-butene in chloride-free acetic acid produced deuterated vinyl acetates via an acetoxypalladation-β-elimination sequence. Analysis of the deuterated products by NMR spectroscopy indicates that the o

Phenylsulfonylmercuration of 1,3-dienes gives mercury adducts, which on treatment with base afford phenylsulfonyldienes. In most cases there action proceeds regioselectively to give 2-(phenylsulfonyl)-1,3-dienes. These are useful synthetic intermedia

Nickel-catalysed addition of deuterium cyanide to (E)-1-deuterio-3,3-dimethylbut-1-ene (1) and subsequent analysis of the dideuteriated nitrile (2) by 1H n.m.r. spectroscopy shows that the addition of deuterium and cyanide occurs in a cis-fashion.

Nickel-catalysed addition of deuterium cyanide to cyclohedxa-1,3-diene was shown to occur with cis stereochemistry, indicating that a cis-migration of co-ordinated cyanide takes place in an intermediate π-allylnickel complex.
