of 1,5-bis(hydroxymethyl)tricyclo[2.1.0.02,5]-pentan-3-one (III) with triphenyl phosphine and carbon tetrachloride results in deep-seated rearrangement to the keto furan, 3-oxybicyclo-[3.3.0]octa-1,4-dien-7-one, VI; the analogous reaction with carbon tetrabromide is normal and yields, the anticipated dibromide IV. Cyclopentadienone intermediates account for the latter reaction and for a dimer formed
用三苯基膦和四氯化碳处理1,5-双(羟甲基)三环[2.1.0.0 2,5 ]-戊三-3-酮(III)导致在深度范围内重排成酮呋喃3-氧代双环-[ 3.3.0] octa-1,4-dien-7-one,VI; 与四溴化碳的类似反应是正常的,并且可以得到预期的二溴化物IV。环戊二烯酮中间体是后者的反应,是碘处理后由1,5-二甲基三环[2.1.0.0 2,5 ]戊酮(Ia)形成的二聚体。
