Abstract
Experimental Section Trimethylpentane (Phillips) was dried over 4A molecular sieves before use. Dimethyl sulfoxide (Mallinkrodt) was distilled from calcium hydride at reduced pressure and stored over 4A molecular sieves. Lithium acetylide-ethylenediamine complex (Alfa), 5- chloro-1-pentene (ICN), 6-chloro-1-hexene (ICN), and Girard reagent" T"(Fisher) were obtained commercially and used as received.
