The influence of transition from ferromagnetism to paramagnetism on the activity of metal catalysts (the Hedvall effect) is explained on the basis of induced spin-polarization of adsorbed radicals. This assumption was verified using the electrochemical reduction of 2,6-diphenylpyrylium cations as a model. This reduction leads to formation of uncharged radicals that undergo fast dimerization in

THE increased reactivity of a solid during and as a consequence of a crystalline transformation is commonly known as the Hedvall effect1-3. In a wider sense this effect may include increased reactivity near a transition point. The typical data quoted in support of the Hedvall effect refer to reactions in the binary systems containing silver salts with BaO, SrO and CaO yielding the Looking for Hedvall effect I?
