| Abstract: | The addition of difluorodiiodomethane (CF2I2,1) with tetrafluoroethene induced by Pb(OAc)4 in acetic acid in an autoclave at 70℃ overnight gives 1,3-diiodohexafluoropropane (ICF2CF2CF2I, 3) in 80% yield 3 can add to alkenes inthe presence of Zn or Na2S2O4 to afford ICF2CF2CF2CH2CHIR (6) and RCHICH2CF2CF2CF2CH2CHIR (7). Its reaction with phenylacetylene also induced by Na2S2O4 affords ICF2CF2CF2CH=CIPh(9) and ICF2CF2CF2CH=C(Ph) CH=CHIPh(10). The substitution of 3 by malonate anion producing ICF2CF2CR=C(CO2Et)2 (12) and HCF2CF2CR=C(CO2Et)2(13)R=CH(CO2Et)2] can be rationalized in term of SRN1 mechanism. |
