A rhodium-catalyzed carbonylative transformation of alkyl halides under low pressure of CO has been developed. This robust catalyst system allows using phenols as the carbonylative coupling partner and, meanwhile, exhibits high functional group tolerance and good chemoselectivity. Substrates even with a large steric hindrance group or multiple reaction sites can be selectively converted into the desired products in good to excellent yields. A gram-scale experiment was performed and delivered an almost quantitative amount of the product. Control experiments were performed as well, and a possible reaction mechanism is proposed.

New 5-alkyl-2-[4-(2-haloalkanoyloxy)phenyl]-1,3-dioxanes were synthesized. Pure trans isomers of these compounds were isolated, whose structure was confirmed by 1H and 13C NMR spectroscopy. Factors influencing mesogenic properties of the products are discussed.
