Next, we examined a series of aroyl chlorides using 1-octene or styrene as the alkene component. As shown in Fig. , this catalytic approach was practical on various aroyl chlorides (59-68), in which the substituents on the aromatic ring exhibited neither a pronounced steric effect nor a noticeable electronic effect on the catalytic efficiency. Besides phenyl acid chlorides, 1naphthoyl chloride and 2-thiophenecarbonyl chloride were compatible, and the structure of 68 was unambiguously determined by single-crystal X-ray analysis.
