Yamamoto coupling polyfluorenes

Ni(0)-promoted Yamamoto coupling have also been appUed for the synthesis of spiro-functionalized polyfluorenes [153]. [Pg.137]

The reductive coupling of arenes is one of the most important methods for preparing polyarenes. A number of methods have been used, but the most widely used is that developed by Yamamoto [92] using bis(cyclooctadiene)nickel(0) (Ni(COD)2) and 2,2 -bipyridyl as illustrated in Scheme 6.14 for the synthesis of a polyfluorene 73 [93],... [Pg.229]
