Photoreduction of Diphenylmethylenimine
The Journal of the Society of Chemical Industry, Japan, 1969 ジフェニルメチレンイミンを2-プロパノール中100W高圧水銀灯で50時間光照射すると,N-ジフェニルメチレン-1,1-ジフェニルメチルアミン,1,1-ジフェニルメチルアミン,1,1,1',1'-テトラフェニルジメチルアミンおよびジフェニルメタンをそれぞれ30,30,6および5%の収率で得た。この光化学反応が溶媒からの水素引抜きによることは,溶媒を2-プロパノールから水素供与能力の小さいメタノール,テトラヒドロフランおよびシクロヘキセンに変えるにしたがって,反応率が低下することより明らかとなった。さらにジフェニルメチレンイミンを低温の剛体溶媒中で光照射して,電子スピン共鳴吸収スペクトルを測定し,g=2.00にΔHmsl=18ガウスの一重項を見い出した。この電子スピン共鳴吸収スペクトルのシグナル強度にも,
