β¦ Synopsis
The effect of different N-pentyl-2-pyridylmethanimine derivatives 2a-f upon the rate of copper(I) mediated atom transfer radical cyclisation (ATRC) of 5 and living atom transfer radical polymerisation (ATRP) of methylmethacrylate were investigated.

## Abstract Summary: The effect of [L]/[Cu^I^] ratio, ligand, the choice of solvent and temperature on the activation rate constants in ATRP with catalyst complexes formed with two pyridylmethanimine ligands [PMI, i.e., __N__βpropylβpyridylmethanimine (NPPMI) and __N__βoctylβpyridylmethanimine (NOP
The rate constants for reaction of a series of Re(CO),L (L=CO, PR3, P(OR),) radicals with various -atom or functional group donors in hexane at room temperature have been measured using laser flash photolysis. The data in each series have been analyzed in terms of the linear free energy relationship
