Ph 3 P/TiCl 4是α-溴代硫代酯Claisen型缩合反应的有效促进剂。在自缩合和交叉型反应的情况下，以良好的产率得到相应的β-酮硫酯。
The Ph 3 P/TiCl 4 combination was found to be an effective promoter for the Claisen-type condensation of α-bromothioesters. Both in the case of self-condensation and crossed-type reactions, corresponding β-ketothioesters were obtained in good yields.
