Abstract:
Eleven compounds of general structure RCON=NC(CN)R 2 ′, where R = C 6 H 5 , CH 3 , C 6 H 5 CH 2 , and R 2 ′ = (CH 3 ) 2 , (CH 2 ) 4 , (CH 2 ) 5 , (CH 2 ) 6 , have been found to decompose in a first-order manner in dilute toluene solution in the temperature range 60–100°. The N-acetyl compounds decompose ca. four times faster than the corresponding N-benzoyl cases. Variation in R 2 ′ causes changes in rate parallel to those observed by Overberger for the analogous bis-α-cyanoalkyl diimides but of smaller magnitude. The products are those expected from homolytic cleavage, and intermediate N-acylketenimines have been trapped by added water in two cases.
