Acetylenic and Polyacetylenic Compounds Derived from Thiophene, Furan, and p-Dibromobenzene Using 1,1-Dichloro-2,2-difluoroethene

Compounds of the type AZCF=CCl2, prepared from AZA (thiophene, furan, and p-dibromobenzene; Z = 2,5-thiophenediyl, 2,5-furandiyl, and p-phenylene; A = H or Br), were converted into CCl2=CFZCCH, CCl2=CFZCCCF=CCl2, and CCl2=CFZCCSi(CH3)3 in a one-flask procedure via LiZCCLi.The products were further converted into acetylenic compounds such as (CH3)3SiCCZCCSi(CH3)3 and (CH3)3SiCCZCC-CCSi(CH3)3. 1-Ethynyl-4-(1,3-butadiynyl)benzene was izolated. 2,5-Diethynylthiophene and -furan were prepared in two steps from thiophene and furan, respectively, via CCl2=CFZCF=CCl2.By treatment with copper (II) acetate hydrate in pyridine, (CCl2=CFZCC-)2 were obtained not only from CCl2=CFZCCH but also from CCl2=CFZCCSi(CH3)3.
