characterised, and deprotonated to give the in situ generated lithium amides, [Li(LMes)] and [Li(LTrip)]. Reaction of these with BBr3 and AlBr3 has given the amido group 13 element halide complexes, [LMesBBr2] and [LAlBr2(THF)] (L = LMes or LTrip), the crystal structures of all of which have been determined. Synthetic routes to two new bulky amidine pro-ligands, ArN = C(But)-N(H)Ar, Ar = C6H2C(H)Ph2}2Me-2
合成了一种非常庞大的仲胺HN(Ar †)(SiPr 3 i)HL †(Ar † = C 6 H 2 C(H)Ph 2 } 2 Pr i -2,6,4),并用KH在甲苯中,得到氨化钾[KL †(η 6 -甲苯)],这是在结构上进行认证。用的BBr的该反应3和AlBr 3,可再现地,得到晶体学表征酰氨基溴硼烷,[L † B(H)BR],和aluminacycle,[AlBr 2 κ 2 -C,NN(H)(SIPR 3i)C 6 H 2 [CPh 2 ] [C(H)Ph 2 ] Pr i -2,6,4}}]分别通过配体C–H活化过程进行。已知的仲胺HN(Dip)(Mes)(HL Mes)和HN(Dip)(Trip)(HL Trip)(Dip = 2,6-二异丙基苯基,Mes =甲苯基,Trip = 2,4,6-三异丙基苯基),已进行了结构表征,并进行了去质子化反应,从而生成了原位生成的锂酰胺[Li(L
