Reactions involving various types of tetraorganotin

A considerable number of papers have appeared which deal with coupling reactions which can be applied to the transfer of two or more types of group from tin to the organic skeleton. Since these are difficult to classify, it seems appropriate to present them in tabular form (Table 4-1). Less conventional applications will be discussed below. 

Bao et al. [178] have used several bis(stannyl) derivatives [2,5-bis(tributylstannyl) thiophene, l,4-bis(tributylstannyl)benzene, other l,4-bis(tributylstannyl)arenes, -bis(tri-butylstannyl)ethene] in the synthesis of functional polymers.
