    • Although deeper investigations and kinetic studies are needed, this rate similarity for the formation of a five- and six-membered ring seems to be against the general trend for classical stereoelectronically controlled cyclization processes. This observation was previously noted in the field of groupIV metal catalyzed hydroamination of aminoalkenes, see Ref.[9a] for an example.
