LuCl3 reacts with t-butyllithium in the presence of ether and tetramethylethylene diamine (tmed) to form , the structure of which has been elucidated through complete X-ray analysis.The crystals are orthorhombic with a 20.995(9), b 18.310(7), c 9.527(2) Angstroem, space group P21ab, Z = 4, D(calcd) 1.17 g cm-3, R = 0.035, and 2471 observed reflections.The compound undergoes 1,2-addition to cinnamic aldehyde, benzalacetone, 1-phenylbutene-2-methyl-3-one, 2-methylbutene-3-one and cyclohexanone, respectively, to give after hydrolysis of the reaction mixture α-t-butyl-substituted enoles.The reaction products were identified by means of GC/MS methods.
