title: Reductive cyclodimerization of arylmethylidenemalononitriles promoted by samarium and catalytic amount of iodine: facile synthesis of cyclopentene derivatives.
abstract: Samarium and a catalytic amount of iodine were used to obtain functionalized cyclopentenes by reductive dimerization followed by intramolecular cyclization of 1,1-dicyanoalkenes under mild conditions.
