Abstract:
Hexabutynylbenzenes I [R = Si(CHMe2)3, Me2SiCMe2CHMe2, CMe3] were prepd. by coupling of hexabromobenzene with butadiynes HC.tplbond.CC.tplbond.CR in the presence of catalyst PdCl2(PPh3)2, CuI, and Et3N. The structures of I (R = SiMe3, CMe2OH) were detd. by UV spectroscopy and crystallog., resp.
