The two-step synthesis of the diols is based on the radical addition of 2,2-dimethyl-1,3-dioxolane (1), a protected ethane-1,2-diol, to perfluoroalk-1-enes R-F-CF=CF2 (RF=CF3, C9F19; 2, 3) and perfluoro[trifluorovinyl (poly)ethers] RFO-CF=CF2 (R-F=C3F7, C3F7O[CF(CF3)CF2], CF3(OCF2CF2)(4); 4-6) with preparative yields above 90% in each step. The additions were initiated photochemically or by dibenzoyl peroxide and were completely chemoselective and almost completely regioselective. 4-Fluoroalkylated dioxolanes obtained (7-11) were deprotected by acid methanolysis to afford 1-polyfluoroalkylethane-1,2-diols (12-16). 1,3-Dioxolane (27) or 2,2,4-trimethyl-1, 3-dioxolane (30) reacted at two centers to yield regioisomeric mixtures of fluoroalkylated dioxolanes. The factors influencing fluoroolefin and dioxolane regioselectivity are discussed. (C) 1999 Elsevier Science S.A. All rights reserved.
