Abstract

Sun lamp illuminated alkoxycarbonylation of aryl, heteroaryl, and vinyl halides was performed under atmospheric pressure of CO in the presence of a cobalt catalyst in situ generated from Co (0Ac) z. Illumination through a Pyrex flask was sufficient to catalyze the reaction. This process avoids the use of COZ (CO)~ and excess CHd, which were required in the earlier procedure. A SRN~ mechanism is proposed.
