Different than others: Dimeric rhodium(II) carboxylates uniquely catalyze the 6‐endo‐dig selective hydroamination of propargylguanidines while tranditional π‐Lewis acids are typically 5‐exo‐dig selective (see scheme, oct=octanoate). Furthermore, this represents a new role for RhII to activate alkynes for addition chemistry.
