The reaction of 3-, 4- and 5-halotropolones with olefins catalyzed by palladium (O) complex gave 3-, 4- and 5-(substituted vinyl) tropolones respectively. Similarly, 2-chlorotropone gave 2-styryltropones. Some tropolonyl- and troponylpalladium-σ-complexes were synthesized.
3-,4-和5-卤代托环酮与由钯(O)配合物催化的烯烃的反应分别得到3-,4-和5-(取代的乙烯基)对苯二酚。类似地,2-氯托酮产生2-苯乙烯基托酮。合成了一些tropolonyl-和对苯甲酰基钯-σ-复合物。
