1,4-Bis(silyl)benzene의 고리화반응에 의한 1,4-Bis(1'-alkyl-2',3',4',5'-tetraphenyl-1'-silacyclopentadienyl)benzenes 리간드의 합성

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. 다양한 bis(silacyclopentadienyl)aromatic 화합물 합성에 필요한 전구체인 1,4-bis(alkyldichlorosilyl)benzene을 합성하였다. 이 전구체에 1,4-dilithio-1,2,3,4-tetraphenyl-1,3-butadiene을 첨가하여 고리화반응을 시킴으로써 리간드로 또는 안정한 silacyclopentadienyl anion 전구체로 사용될 1,4-bis(1'-alkyl-2',3',4',5'-tetraphenyl-1'-silacyclopentadienyl)benzene을 합성하였다.
