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)(mu-OCPhMe(2))(2)Mg(MeCN)(4) (2) and {2[I(MeCN)Mg(mu-OCPh(2)Me)(2)Mg(MeCN)I] (3) x [I(MeCN)Mg(mu-OCPh(2)Me)(2)Mg(mu-OCPh(2)Me)(2)Mg(MeCN)I] (4) x 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.
