EPR and pulsed ENDOR study of intermediates from reactions of aromatic azides with group 13 metal trichlorides [PDF]

open access: yes, 2013
The reactions of group 13 metal trichlorides with aromatic azides were examined by CW EPR and pulsed ENDOR spectroscopies. Complex EPR spectra were obtained from reactions of aluminium, gallium and indium trichlorides with phenyl azides containing a ...

End-group functionalization of poly(2-oxazoline)s using methyl bromoacetate as initiator followed by direct amidation [PDF]

open access: yes, 2019
Poly(2-alkyl/aryl-2-oxazoline)s (PAOx) are an alluring class of polymers for many applications due to the broad chemical diversity that is accessible for these polymers by simply changing the initiator, terminating agent and the monomer(s) used in their ...
