1,3-Diphenylbenz[ƒ]inden-2-one (5) reversibly generated by thermal dissociation of its (π4 +π4)-dimer (4) adds stereospecifically to cis- and trans-but-2-ene; the related adducts (6) and (7) undergo smooth photodecarbonylation to the long-lived 2,3-naphthoquinodimethanes (2; R1= R2= Me) and (2; R1, R2=[CH2]4).
1,3- Diphenylbenz [ƒ]茚-2-酮(5通过的热解离产生的可逆)它的(π 4 + π 4)-dimer(4)立体有择地添加到顺式-和反式-丁-2-烯; 相关的加合物(6)和(7)经历长寿2,3-萘醌二甲烷(2; R 1 = R 2 = Me)和(2; R 1,R 2 = [CH 2 ] 4)的光脱羰反应。
