Practical and simple techniques are described for using nonmodified domestic microwave ovens as safe and convenient laboratory devices to obtain numerous esters.High pressures are avoided by conducting reactions with reactants impregnated on solid mineral supports in "dry media" or by phase transfer catalysis (PTC) in the absence of organic solvents.Two kinds of microwave effects are involved: (1) displacement of the equilibrium by evaporation of volatile polar molecules (water or alcohols) in esterfications and transesterfications; (2) acceleration of ionic reactions in carboxylate alkylations.As solvents are avoided, there is no need for sealed vessels and water separators.
FACILE CONVERSION OF TETRAHYDROPYRANYL AND SILYL ETHERS INTO ESTERS USING ACID CHLORIDES AND ZINC CHLORIDE
Kim, Sunggak,Lee, Won Jae
, p. 659 - 666 (2007/10/02)
Tetrahydropyranyl and silyl ethers were cleanly converted into the corresponding esters using acid chlorides and a catalytic amount of zinc chloride in acetonitrile.
