An unprecedented cross-dehydrogenative-coupling (CDC) reaction of saturated aldehyde beta-C-H with arenes to form cinnamaldehydes via the cleavages of four C-H bonds has been developed. The reaction possesses complete E-stereoselectivity for the C = C double bond. The protocol is featured by atom and step economy, mild reaction conditions, and convenient operation.
