Photolysis (350 nm) of 3-noradamantyldiazirine (5) in argon at 14 K produces adamantene (1) (λmax = 320 nm; IR, ν = 1478 cm-1) and protoadamant-3-ene (8) (λmax = 220 nm); IR, ν = 1580 cm-1). Strained alkenes 1 and 8 can be interconverted photochemically in argon at 14 K. Laser flash photolysis (351 nm) of 5 in benzene solution produces 1. The decay of 1 is monitored at 325 nm. Absolute rate constants
3-noradamantyldiazirine (5) 在 14 K 的氩气中光解 (350 nm) 产生金刚烯 (1) (λmax = 320 nm; IR, ν = 1478 cm-1) 和 protoadamant-3-ene (8) (λmax = 220纳米);红外,ν = 1580 cm-1)。应变烯烃 1 和 8 可以在 14 K 的氩气中进行光化学相互转化。5 在苯溶液中的激光闪光光解 (351 nm) 产生 1。在 325 nm 处监测 1 的衰减。报告了 1 与甲醇、1,3-环己二烯、三(三甲基甲硅烷基)硅烷、乙酸和氧气的反应的绝对速率常数。
