Abstract
Photodissociation of HN3 with ultraviolet light in the presence of both cis- and
trans-2-butene was undertaken in matrices of argon and xenon. Based on previous
studies on the reactions of NH and on spectral evidence along with ab initio molecular
orbital calculations, major photoproducts were identified as cis- and trans-2,3-
buteneimine. It was concluded that the major product upon photolysis of HN3/C/5-2-
butene/Ar mixtures is c/s-2,3-buteneimine, and that the major product in trans-2-
butene/Ar mixtures was the corresponding fraws-2,3-buteneimine. Complete
stereochemical retention was observed for the cis- product while in the trans- mixture
both cis- and /r«w5-2,3-buteneimine were observed. There are other minor products in
the argon matrices that have yet to be assigned, N2H2 and HONO being likely suspects.
Product absorption intensities in xenon were much weaker than in argon matrices. The
buteneimine products did appear in the xenon matrices, but no rearrangement was
observed.
