A Concise Synthesis of N-Methyl-2,3-diferrocenyl-4,4-dicyanopyrrolidine through 3+2 Cycloaddition of Azomethine Ylides

摘要

Microwave-assisted synthesis of N-methyl-2,3-diferrocenyl-4,4-dicyanopyrrolidine has been accomplished in moderate yields via a facile 1,3-dipolar cycloaddition and its crystal structure was determined by single-crystal X-ray diffraction (CCDC no. 1583719). It crystallizes: C27H25Fe2N3, Mr = 503.20, orthorhombic, P2(1)2(1)2(1), a = 10.4873(9), b = 10.5251(10), c = 20.8587(19) angstrom, V = 2302.4(4) angstrom(3), rho = 1.452 g cm(-3), Z = 4, T = 298(2) K.
