## Abstract Effects of substituents in diene and dienophile on the regio‐ and stereo‐selectivity of Diels‐Alder reactions have been studied on cycloadditions of alkoxy‐substituted 1,3‐butadienes (**1**) and 2‐substituted cyanoethenes (**2**). The regioselectivity is always very high, and is determi

## Abstract The kinetics of [4 + 2] cycloadditions in several solvents have been studied for reactions between ring‐substituted β,β‐dicyanostyrenes (**2a–j**) and a series of methoxybutadienes (**1a–e**), differing in electron‐donating properties, conformational preference and polarity. All reactio
