✦ Synopsis

Upon treatment with butyllithium followed by adding zinc halide, conjugated polyenic tellurides smoothly undergo a Pd(0)-catalyzed cross coupling reaction with acyl chlorides to form the pure thermodynamically more stable conjugated polyenic ketones in good yield, regardless of the configuration of the telluride used.
