One-pot oxime formation and SPANOC with DIBO (2)

Entry	R	k (M-1 s-1)a, b, c	Yield (%)d
1	C6H5 (6a)	3.44 ± 0.03	55
2	2-Me-C6H4 (6g)	3.20 ± 0.03	51
3	C6H5-CH2CH2 (6h)	1.38 ± 0.01	90

^aRate constant was determined from isolated oximes;

^bSecond order rate constants were determined from pseudo first order rate constants at various concentration of nitrile oxides at 25 ± 0.1°C.

^cPseudo first order kinetics were determined using UV-Vis spectroscopy following the decay of the absorbance of 2 at 305 nm; [2] = 6.0 × 10^-5 M; for details on the concentrations of nitrile oxides, see supporting information.

^dIsolated yields of combined isomers.
