Organometallic Compounds of Group VA Elements

In some cases, metallic tin reacts directly with an alkyl halide to produce mixed alkyl halide compounds. 

Both the dimethylsilanes and germanes are much more reactive than the tetraalkyls and hydrolyze readily. 

The great utility of dialkyldichlorosilane (b.p. 70 °C) lies in the fact that it is an intermediate in the production of silicon polymers. 

Alkyl tin compounds react with tin tetrahalides to produce a range of products that have the general formula R SnX4 n. These compounds react with LiAlH4 to produce tin hydrides. Other aspects of the organic chemistry of tin are presented in Chapter 14. 

There are many organometallic compounds of arsenic, antimony, and bismuth known that constitute series having chemical properties that differ markedly. These compounds generally decrease in stability in the order As Sb Bi, which agrees with the increasing difference in size of the atoms and carbon atoms. Arsenic compounds include both aliphatic derivatives and heterocycles such as arsabenzene,
