Abstract
EHT calculation have been carried out on phenyl chloro-thiol, phenyl chloro-thiono and phenyl dithioformates to explain the conformations and reactivity of the compounds. Results of calculation lead us to conclude that the mechanism of SN reaction of these compounds are likely to be the $S_N2$ type and trans form is more stable than cis form for all molecules.
Phenyl chloro-thiol, phenyl chloro-thiono 와 phenyl dithioformate에 분자궤도 함수론을 적용하여 계산 연구한 결과 모든 경우 trans형이 더 안정하며 또 SN반응기구는$ S_N2$형으로 일어날 가능성이 큼을 밝혔다
