The title tetrone compound, C32H22N2O4S· 0.5C8H10, is the major product (50% yield) of an attempted Diels-Alder reaction of 2-(α-styr-yl)thio-phene with N-phenyl-male-imide (2 equivalents) in toluene. Recrystallization of the resulting powder from p-xylene gave the title hemisolvate; the p-xylene mol-ecule is located about an inversion center. In the crystal, the primary tetrone contacts are between a carbonyl O atom and the four flagpole H atoms of the bi-cyclo-[2.2.2]octene core, forming chains along [001].
标题化合物C32H22N2O4S·0.5C8H10是2-(α-苯乙烯基)噻吩与N-苯基马来酰亚胺(2当量)在甲苯中尝试进行狄尔斯-阿尔德反应的主要产物(产率50%)。从对二甲苯中重结晶得到的粉末得到标题半溶剂化物;对二甲苯分子位于一个反演中心周围。在晶体中,主要的四酮接触是在一个羰基O原子与双环-[2.2.2]辛烯核心的四个旗杆H原子之间,沿[001]形成链。
