摘要：
The title compound RFC(=O)N=C(NMe2)(2) (2) was prepared in virtually quantitative yield by reacting RFC(=0)C1 with two equivalents of N,N,N',N'-tetramethylguanidine and structurally characterized by X-ray diffraction. Due to severe steric crowding, the carbonyl group approaches a perpendicular arrangement (torsion angle of 70.1(2)degrees) with respect to the phenyl ring. (C) 2002 Elsevier Science B.V.
