Photolysis of 3-pyridyldiazomethane in an Ar matrix at 7-10 K gives 3-pyridylcarbene. Further photolysis causes ring opening to nitrile ylide 26 (formonitrile pent-2-en-4-ynylide) as the major reaction together with a minor amount of ring expansion to 1-azacyclohepta-1,3,4,6-tetraene, 27. Matrix photolysis of 3-azidopyridine leads to ring opening to formonitrile N-cyanovinylmethylide, 33.
3-吡啶基重氮甲烷在 Ar 基质中在 7-10 K 下光解得到 3-吡啶基卡宾。进一步的光解导致腈叶立德 26(甲腈 pent-2-en-4-ynylide)开环,作为主要反应,同时少量扩环成 1-azacyclohepta-1,3,4,6-tetraene, 27。 3-叠氮吡啶的基质光解导致开环形成甲腈 N-氰基乙烯基甲基化物,33。
