Abstract
질소를 방향족고리에 포함하고 있는 헤테로 화합물인 트란스-1,2-비스피라질 에틸렌을 쿠멘, 이소프로판올, 시멘용매등에 녹여 빛을 쪼여준 결과 광화학적 환원이 일어나 1,2-비스피라질 에탄이 됨을 알았다. 알칼리 금속염이 이 환원반응에 미치는 영향, 용매효과, 증감제와 아줄렌등의 영향으로 부터 이 환원 반응은 (π,π*)1상태로부터 일어남을 알았다.

Photochemical reduction of 1,2-bispyrazylethylene,a stilbene like heterocompound, was studied in hydrogen donating solvents and reduction product, 1, 2-bispyrazylethane, was identified. Salt and solvent effects on the quantum yields of the reduction, sensitization and quenching studies showed that the reactive state for the photochemical reduction of the compound is (n,π*)1 state rather than (π,π*)1 state.
