  描述：

  4-tert-butyl-5-[3-(3-cyano-4,5-dihydro-5,5-diphenyl-3H-pyrazol-3-yl)phenyl]-3,3-dimethyl-2,3-dihydrofuran 在 氧气 、 tetraphenylporphyrin 作用下， 以 二氯甲烷 为溶剂， 以99.3%的产率得到5-tert-butyl-1-[3-(3-cyano-4,5-dihydro-5,5-diphenyl-3H-pyrazol-3-yl)phenyl]-4,4-dimethyl-2,6,7-trioxabicyclo[3.2.0]heptane

  Intramolecular charge-transfer-induced chemiluminescent decomposition of 1,2-dioxetanes bearing a phenylmethanide anion

  摘要：

  Dioxetanes (1) bearing a phenyl moiety substituted with a methylene or methine having an electron-withdrawing group(s) (-CH2-Ew or -CH(X)-Ew) and dioxetane (2) bearing a 3-(1-cyanoethenyl)phenyl group were synthesized. Treatment of dioxetanes (1) with tetrabutylammonium fluoride (TBAF) caused their decomposition with accompanying emission of light with maximum wavelength at 530-758 nm. The Michael addition of a bis(methoxycarbonyl)methanide anion to dioxetane (2) produced initially ail unstable dioxetane bearing a phenylmethanide anion, decomposition of which gave light with maximum wavelength at 710-740 nm. Intramolecular cyclopropanation without decomposition of the dioxetane ring took place concurrently for the Michael reaction-induced decomposition of 2 with the bis(methoxycarbonyl)chloromethanide anion.
