Rhodium-catalyzed hydrophosphorylation of terminal alkynes leading to highly selective formation of (E)-alkenylphosphonates: Complete reversal of regioselectivity to the palladium-catalyzed counterpart

Insights into the mechanism of the rhodium-catalyzed hydrophosphorylation of alkynes with the cylclic hydrogen phosphonate 1 are provided by isolable RhIII intermediates 2 and 3. The reactions proceed at room temperature and give high yields of exclusively (E)-alkenyl phosphonates 4, which are not readily, L = phosphane or hydrogen-phosphonic acid.
