compounds depending on the nature of R and R'. If R = R' = (t)Bu, a closo compound with one vertex occupied by "[Pd(P(t)Bu(3))(2)]" is obtained. When aryl groups are present in the starting phosphine complex, the zwitterionic non-metal-containing compounds are obtained. The crystal structure of one of them has been determined, and the compound has been proven to be 7,8-&mgr;-(S(CH(2))(3))-11-PPh(3)-7,8-C(2)B(9)H(9)

生物是由1-(SH)-1,2-C(2)B(10)H(11)合成的。后者与(n)BuLi和
1,3-二溴丙烷的反应生成1,2-&mgr;-(S(CH(2))(3))-1,2-C(2)B(10)H (10)。部分降解会导致[7,8-&mgr ;-( S(CH(2))(3))-7,8-C(2)B(9)H(10)](-)。[7,8-&mgr ;-( S(CH(2))(3))-7,8-C(2)B(9)H(10)](-)与[PdCl(2)( PRR'(2))(2)]取决于R和R'的性质,会产生不同的化合物。如果R = R’=(t)Bu,则获得一个顶点被“ [Pd(P(t)Bu(3))(2)]占据的closo化合物。当起始膦配合物中存在芳基时,获得两性离子非含
