An electrochemical cinnamyl C—Hamination reaction in the absence of transition metal catalyst and oxidant was reported. The choice of carbonyl sulfamate as nitrogen source is the key to achieve desired chemoselectivity. A series of terminal amine derivatives are prepared using this protocol and the sulfonyl group can be removed with basic hydrolysis. The reaction is suggested to proceed via a continuous

A catalytic intermolecular amination of nonactivated tertiary C(sp3)–H bonds (BDE of 96 kcal·mol–1) is reported for substrates displaying an activated benzylic site (BDE of 85 kcal·mol–1). The tertiary C(sp3)–H bond is selectively functionalized to afford α,α,α-trisubstituted amides in high yields. This unusual site-selectivity results from the synergistic combination of Rh2(S-tfpttl)4, a rhodium(II)
