Dialkyl dithiophosphates selectively ring open vinyl oxetanes in excellent yields under mild reaction conditions to form useful allylic thiophosphate products with high Z-selectivity.
A novel and regioselective approach to carbonyl-containing alkylchlorides via silver-catalyzed ring-opening chlorination of cycloalkanols is reported. Concurrent C(sp3)–C(sp3) bond cleavage and C(sp3)–Cl bond formation efficiently occur with good yields under mild conditions, and the chlorinated products are readily transformed into other useful synthetic intermediates and drugs. The reaction features
