The kinetics of the [2 + + 4] cycloadditions of 1,3-dithian-2-cycloaddition pathway by the correlation lg k = s (E + N). Though a concerted cycloaddition pathway is not excluded ylium ions (1) with 1,3-dienes was investigated photometrically in dichloromethane. The second-order rate by this finding,
## Abstract A novel reaction of acylium and thioacylium ions, polar [4 + 2^+^] DielsβAlder cycloaddition with 1,3βdienes and __O__βheterodienes, has been systematically investigated in the gas phase (Eberlin MN, Cooks RG. __J. Am. Chem. Soc.__ 1993; 115: 9226). This polar cycloaddition, yet without
