The radical carbohydroxylation of styrenes with aryldiazonium salts has been achieved under mild thermal conditions. A broad range of aryldiazonium salts was tolerated, and the reaction principle based on a radical-polar crossover mechanism could be extended to carboetherification as well as to a two-step, metal-free variant of the Meerwein arylation leading to stilbenes.

Metal and catalyst‐freecarbohydroxylations and carboetherifications at room temperature have been achieved by a combination of beneficial factors including high aryl diazonium concentration and visiblelight irradiation. The acceleration of the reaction by visiblelight irradiation is particularly remarkable against the background that neither the aryldiazonium salt nor the alkene show absorptions

C(CH3)=CH, respectively, in which the C(CH3)=CH has a side‐group CH3 at the carbon‐carbon double bond. A series of XSMBY were synthesized, and their longest wavelength maximum λmax (nm) in ultravioletabsorptionspectra were measured in this work. We investigated the change regularity of the νmax (cm‐1, νmax = 1/λmax) of XSMBY and compared it with that of XSBY. The results indicate that (1) there is no
