1,1-디페닐-2-비닐시클로프로판을 벤젠, n-헥산, 아세토니트릴에 녹여 253.7nm의 빛을 쪼이면 1,1-디페닐에틸렌이 주생성물로 얻어지며 4,4-디페닐시크로펜텐, 저분자량의 고분자 물질 및 미확인 생성물이 소량으로 얻어진다. 증감제를 쓴 광화학반응과 UV 흡광스펙트럼으로부터 시클로프로판고리가 비닐기나 벤젠고리와 어느 정도 걸러짝짓기를 하고 있으나 시클로프로판고리를 통한 걸러짝짓기는 일어나지 않는다
The photochemical reactions and spectral properties of 1,1-diphenyl-2-vinylcyclopropane were studied. Upon direct irradiation of the compound at 253.7nm, 1,1-diphenylethylene was formed as a major product along with a small amount of 4,4-diphenylcyclopentene. Sensitized photoreactions showed quite a different phenomena from those of conjugated dienes supporting the spectral results that the cyclopropane ring does not transmit the conjugation in the compound
