  The Ullmann Coupling Reaction:  A New Approach to Tetraarylstannanes

  摘要：

  Several iodobenzenes form tetraarylstannanes, in addition to other products, under reaction conditions typically employed for the Ullmann reaction, i.e., activated copper bronze (a copper-tin alloy) and 7 days at 230 degrees C. The isolated yields of the tetraarylstannanes were low to good (8-58%). Significantly higher yields (54-64%) of tetraphenylstannane were obtained by the direct reaction of iodobenzene with an excess of tin powder (iodobenzene: tin = 1: 1 w/w) under the same conditions. Crystal structure analysis reveals that tetrakis(4-carbomethoxyphenyl) stannane crystallizes in a tetragonal space group and has (4) over bar symmetry, which is the case for many symmetrical tetraarylstannanes. However, tetrakis(2,4dichlorophenyl) stannane, tetrakis(3,4-dichlorophenyl) stannane, and tetrakis(2,4-dimethylphenyl) stannane do not crystallize in a tetragonal space group and do not have real 4h symmetry.
