P. Delacruz et al., CYCLOADDITIONS TO [60]FULLERENE USING MICROWAVE IRRADIATION - A CONVENIENT AND EXPEDITIOUS PROCEDURE, Tetrahedron, 53(7), 1997, pp. 2599-2608
Several Diels-Alder and 1,3-dipolar cycloadditions to C-60 were perfor
med, under microwave irradiation, in a modified domestic microwave ove
n and a focused microwave reactor. Reactions proceed within minutes to
afford the respective cycloadducts in similar or increased yields rel
ated to the described methods by conventional heating. This methodolog
y simplifies the procedure and overcomes the drawbacks resulting from
the long reaction times required under classical heating conditions. (
