Intramolecular reaction

For the formation of different ring sizes via cyclization of substrates of varying tether length, the order of reaction rates (rate constants k n for the formation of an n-membered ring) is usually k 5 >k 6 >k 3 >k 7 >k 4 as shown below for a series of ω-bromoalkylamin This somewhat complicated rate trend reflects the interplay of these ....
