Recent Developments in Azomethine Ylide-Initiated Double Cycloadditions [PDF]

open access: yesMolecules
Azomethine ylides (AMYs) have a nitrogen–carbon double bond and an electron lone pair on the nitrogen atom. They are essential 1,3-dipoles for [3+2] cycloadditions in the synthesis of pyrrolidine-containing heterocycles.

Nylon 4,I: an amorphous polyamide [PDF]

open access: yes, 1984
The melt polymerization of nylon 4, I was studied, starting with nylon-salt and nylon prepolymers (ηinh=0.25). With nylon-salt only low molecular polymers were obtained, while with prepolymers the inherent viscosity could be raised to 0.77 (3h, 270°, vac.
