Organoaluminum mercury

Organoaluminum compounds, particularly AlEt3, are commercially very important as activators for olefin polymerization catalysts and are produced on a large scale, in spite of their pyrophoric nature and violent reaction with water. In the laboratory organoaluminum compounds can be made from mercury alkyls by transmetallation ... 

Other organometallic reagents such as organoaluminum reagents (equation 17)" or mercury reagents (equation 18) yield Sb(III) and Bi(III) eompounds, but these reagents have not been used frequently in recent years. 

Transfer from Organoalumlnum Compounds. Organoaluminums are used to prepare organozinc, -cadmium and -mercury compounds e.g., trimethylaluminum reacts with Zn(OAc)2 or Znij to give MejZn. Diethylzinc can be prepared from [Et A Na (92% yield) or Et2AlCl (10%) with zinc halides. Another example is ... 

In a process that served for the preparation of the first organoaluminum compound (1865),230 the trialkyl and, more so, the triaryl compounds can be conveniently obtained by treating metallic aluminum with the relevant organo-mercury compound.147,231,232 This method is too expensive when large...
