  The reaction of 6-(2,3,3-trifluorocyclobutenyl)-4,5-diazaspiro[2.4]hept-4-ene with NaOMe in MeOH results in a mixture of isomeric (6E)- and (6Z)-6-(2-fluoro-3,3-dimethoxycyclobutylidene)-4,5-diazaspiro[2.4]hept-4-ene due to the formal substitution of methoxy groups for two geminal fluorine atoms. Both of the isomers selectively add acetyl chloride at the azo-olefin unit to give 4-acetyl-6-(1-chloro-2-fluoro-3

  6-(2,3,3-三氟环丁烯基)-4,5-二氮杂螺[2.4]庚-4-烯与NaOMe在MeOH中的反应产生异构体(6E)-和(6Z)-6-( 2-氟-3,3-二甲氧基环亚丁基)-4,5-二氮杂螺[2.4]庚-4-烯由于甲氧基对两个孪生氟原子的形式取代。两种异构体都选择性地在偶氮烯烃单元添加乙酰氯，得到 4-乙酰基-6-(1-氯-2-氟-3,3-二甲氧基环丁基)-4,5-二氮杂螺[2.4]hept-4-烯作为反式异构体，产率超过 95%。(© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2003)

  The reactions of diazomethane and diazocyclopropane generated in situ with 1,1,2,2-tetrafluoro-3-vinylcyclobutane (1) and 2,3,3-trifluoro-1-vinylcyclobutene (2) proceeded at the double bond of the substituent as the 1,3-dipolar cycloaddition to form the corresponding 1-pyrazolines. Under the conditions of thermolysis (340-400 degreesC), the resulting cyclobutylpyrazolines 4 and 5 selectively lost the dinitrogen molecule to generate 3-cyclopropyl-1,1,2,2-tetrafluorocyclobutane (6) or 1,1, 2,2-tetrafluoro-3-spiropentylcyclobutane (7), respectively, in high yields. In the presence of Pd(acac)(2), the reactions of these fluorine-containing unsaturated compounds and 2-chloro-1,1,2-trifluoro-3-vinylcyclobutane (3) with diazomethane gave rise directly to cyclopropane derivatives 6, 11, and 12, respectively. The reactions of compounds 1 and 2 with methyl diazoacetate in the presence of Rh-2(OAc)(4) proceeded analogously to yield cis- and trans-disubstituted cyclopropanes.
