Abstract
Abstract Treatment of m-alkenyl (or m-alkynyl) vinyl ethers (m = 3,4) with a Ti(II) reagent generated most likely bicyclic oxatitanacycles, which eliminate the alkoxide tether to effect the selective vinyltitanation of the alkene or alkyne moiety to give m-vinyl-1-alkanols or m-vinyl-m-alken-1-ols.
