Abstract
|
|
|
|
The 1,4-bis(alkyldichlorosilyl)benzene was synthesized to be a precursor of the bis(silacyclopentadienyl) aromatic system. The cyclization reaction of the precursor with 1,4-dilithio-1,2,3,4-tetraphenyl-1,3-butadiene produced the 1,4-bis(1'-alkyl-2',3',4',5'-tetraphenyl-1'-silacyclopentadienyl)benzene as the ligand of organotransition metal compound and the precursor of the stable silacyclopentadienyl anion.
