Abstract

The complexes R(Ph)MeCOMg(Et~2~O)I [1, R = Me (a), Ph (b)] were obtained by the reaction of R(Ph)C=O with MeMgI in diethyl ether in good yields. Crystallisation of 1 from acetonitrile resulted in single crystals of di‐ and trinuclear complexes I~2~(μ‐OCPhMe~2~)~2~Mg(MeCN)~4~ (2) and {2[I(MeCN)Mg(μ‐OCPh~2~Me)~2~Mg(MeCN)I] (3) × [I(MeCN)Mg(μ‐OCPh~2~Me)~2~Mg(μ‐OCPh~2~Me)~2~Mg(MeCN)I] (4) × 2CH~2~Cl~2~} in which the metal centres are linked by alkoxy substituents. The thermal decomposition of the complexes 1 was studied by successive detection of the EI mass spectra of diethyl ether, the olefins 5, the tertiary alcohols 6, and the formal olefin dimers 7.
