t Bu, Me ) with 1, 2, or 3 molar equivalents of 2-mercaptopyridine (HSpy) yielded Ga(R)2(Spy) [ R = t Bu ( 1 ), Me ( 2 ) ], Ga(R)(Spy)2 [ R = t Bu ( 3 ), Me ( 4 ) ], and Ga(Spy)3, (5), respectively. Reaction of GaCl3 and HSpy in the presence of NEt3 does yield Ga(Sp)3 if excess HSp is employed, otherwise Ga(Cl)(Spy)2 (NEt3) (6) may be isolated. The indium compound, In(Spy)3 (7), may be prepared both
摘要GaR3(R = t Bu,Me)与1、2或3摩尔当量的2-巯基吡啶(HSpy)反应生成Ga(R)2(Spy)[R = t Bu(1),Me(2 )],Ga(R)(Spy)2 [R = t Bu(3),Me(4)]和Ga(Spy)3,(5)。如果使用过量的HSp,则在NEt3存在下,GaCl3和HSpy的反应的确会生成Ga(Sp)3,否则可以分离出Ga(Cl)(Spy)2(NEt3)(6)。铟化合物In(Spy)3(7)既可以以与化合物5类似的方式制备,也可以在NEt 3存在下由HSpy与InCL或InCl 3反应制备。在除化合物3以外的所有化合物中,2-巯基吡啶仅起螯合配体的作用。Ga(t Bu)3与Ph2P(S)的反应产生[Ph2P(S)S] 2,但只有痕量的预期产物[(t Bu)2 Ga(μ-S 2 PPh 2)] 2(8)。相比之下,Ga(t Bu)3与HO(S)PPh2(E =
