[Co(P1)]-Catalyzed C–H Amination of Various Aldehydes with Pentafluorophenyl Azide (2a)^a,^b

^aAll reactions were carried out in PhCl using 3 mol % of [Co(P1)] as catalyst with 1.0 equiv. of aldehyde (0.2 M) and 1.2 equiv. of azide for 24 h at 80 °C.

^bIsolated yields.

^cAt 100 °C.

^dSmall amounts of aziridine and unidentified compounds were observed by NMR.
