M. Ayerbe et Fp. Cossio, 4M LITHIUM PERCHLORATE-NITROMETHANE - AN EFFICIENT SOLVENT IN DIELS-ALDER REACTIONS USING NITROALKENES AS DIENOPHILES, Tetrahedron letters, 36(25), 1995, pp. 4447-4450
Diels-Alder reactions in which nitroalkenes act as dienophiles are sub
stantially accelerated in 4M lithium perchlorate-nitromethane solution
s. This acceleration is higher than that observed when the known 5M li
thium perchlorate-diethyl ether system is used.
