摘要：
2-(N-Phenylamino)propanoic acid la and 3-(N-phenylamino)-propanoic acid 2a together with four of their aryl analogues were pyrolysed in the gas-phase. The reactions were homogeneous and free from catalytic and radical pathways. Analysis of the pyrolysate of 1 showed the elimination products to be carbon monoxide, acetaldehyde and aniline, while the pyrolysate of 2 reveals the formation of acrylic acid in addition to aniline. Theoretical study of the pyrolysis of 2 using an ab initio SCF method lend support to a reaction pathway involving a 4-membered cyclic transition state. (C) 2004 Elsevier Ltd. All rights reserved.
