✦ Synopsis

Abstract

The reaction of 2‐bromoethylamine 1 with methylisothiocyanate 2 under mild condition gave 2‐methyl‐amino‐2‐thiazoline 3 as the major product together with two kinds of byproducts, 3‐(N‐methylthiocar‐bamoyl)‐2‐methyliminothiazolidine 4 and N,N′‐dimethyl‐N‐(2‐thiazolin‐2‐yl)thiourea 5. Thermal isomer‐ization of 5 to 4 was observed. The structures of the byproducts were confirmed by X‐ray crystallography.

The structures and stability of fullerene derivatives were obtained from the results of density functional theory calculations that were performed on 6 non-classical and 306 classical isomers of C 58 X 18 (X = H, F, Cl). The calculated results demonstrated that the most energetically stable isomers
