초록
제초성 비치환(H) benzenesulfonyl urea 분자, 1은 sulfonyl group 인접의 amino group과 pyrimidinyl group의 N원자 사이에 회합(H-결합)된 형태(II-keto)가 제일 안정하였으며 phenyl 치환
The most stable stereo conformer in non substituted benzenesulfonyl urea, 1 was the II-keto form, which the molecule was intramolecular associated(H-bond) coformer between imide group and N atom on the Pyrimidine ring. The hydrolytic degradation of 2 derivatives were proceeds by nucleophilic addition reaction(p<0) with orbital controlled intermolecular interaction between LUMO with electron donating
