SYNTHESES, PROPERTIES, AND CRYSTAL-STRUCTURES OF THE TITANIUM(III) AMIDO COMPLEXES TI[N(SIME(3))(2)](3), [TICL2(N(SIME(3))(2))(THF)(2)], AND [NA(12-CROWN-4)(2)][TICL2(N(SIME(3))(2))(2)]

TiCl3(THF)(3) reads with NaN(SiMe(3))(2) to furnish [TiCl2{N(SiMe(3))( 2)} (THF)(2)] (i), whereas in the presence of 12-crown-4 the ionic ami do complex [Na(12-crown-4)(2)] [TiCl2{N(SiMe(3))(2)}(2)] (5) is obtain ed besides [Na(12-crown-4)(2)][TiCl4(THF)] (4). On the other hand, the titanium(III) amido complex Ti[N(SiMe(3))(2)](3) (2), the crystal str ucture of which was solved, reacts with NaN(SiMe,), in the presence of 12-crown-4 with deprotonation of one of the methyl groups to give the carbometalated complex )][Ti{N(SiMe(3))(2)}(2){N(SiMe(3))(SiMe(2)CH(2 ))}] (3).
