摘要

In alliance with tertiary amines, TiCl4 is well-known to mediate aldol type condensation reactions1 and oxidative coupling of certain ester enolates. 2 Recently, it was observed in this laboratory that the TiCl4/Et3N reagent system is useful for the oxidative coupling of aryl methyl ketimines to 2, 5-diarylpyrroles3a and for the direct metalation of 1-alkynes. 3b Also, it was observed that trialkylamines are oxidized to iminium ions by TiCl4 with concomitant ...
