provides the bismuth oxido cluster [Bi4O2OCMe2(2-C4H3S)}8] (2). In contrast, the reaction of Bi(OtBu)3 and Bi[N(SiMe3)2]3 with the silanols HOSiMe2(2-C4H3X) (X = O, S, Se, and NMe), HOSiMe2(2-C4H2S-5-SiMe3) and HOSiMe2(3-C4H3S) leads to the formation of tris(heteroaryl)bismuthines Bi(2-C4H2X-5-R)3 [where X = O, R = H (3); X = S, R = H (4); X = S, R = SiMe3 (5); X = NMe, R = H (6); X = Se, R = H (7)] and
通过三个当量的反应形成醇盐Bi [OCMe 2(2-C 4 H 3 S)] 3(1)。用Bi(O t Bu)3制备醇HOCMe 2(2-C 4 H 3 S),然后水解得到铋氧化簇[Bi 4 O 2 OCMe 2(2-C 4 H 3 S)} 8 ] (2)。相反,Bi(O t Bu)3和Bi [N(SiMe 3)2 ] 3的反应与硅烷醇HOSiMe 2(2-C 4 H 3 X)(X = O,S,Se和NMe),HOSiMe 2(2-C 4 H 2 S-5-SiMe 3)和HOSiMe 2(3-C 4 H 3 S)导致形成三(杂芳基)双突变蛋白Bi(2-C 4 H 2 X-5-R)3 [其中X = O,R = H(3); X = S,R = H(4);X = S,R = SiMe 3(5);X = NMe,R = H(6); X = Se,R = H(7)]和Bi(3-C 4 H 3 S)3(
