Hg(CH2SR)2, (R = Me (1), R = Ph (2)), prepared by reaction of HgCl2 with [Li2(CH2SR)2(tmeda)2], reacts with magnesium activated by mercury in boiling THF to give [Mg(CH2SR)2(thf)3] (R = Me (3), R = Ph (4)). 3 readily splitts off THF in vacuo to give the solvate free complex [Mg(CH2SMe)2] (3′). The complexes 3′ and 4 are fully characterized by microanalysis and NMR spectroscopy (1H, 13C). The X-ray structure analyses of 3 and 4 reveal mononuclear compounds with two symmetry independent molecules in the unit cell of 3. In both complexes the coordination of Mg is trigonal-bipyramidal. The two apical positions are occupied by THF and the three equatorial positions by one THF and the two thiomethyl ligands. The C-Mg-C angles are slightly greater (123.9(1)-131.0(2)°) than the ideal angle for equatorial atoms in a trigonal-bipyramidal coordination. In neither case, the sulfur atoms are involved in the coordination of Mg.

2PhSCH2Li*1.5N(CH2CH2)3N*0.5THF (I) and PhSCH2Li*2THF (II) can be isolated in a crystalline state from solutions of PhSCH2Li which have been obtained by metallation of thioanisole with BuLi/N(CH2CH2)3N and PhLi respectively, according to Corey and Seebach
