The photochemical synthesis method for producing H2O2 using benzyl compounds as the hydrogen source described in this invention uses oxygen or air as the oxygen source and ultraviolet light as the energy driving force. The process steps are as follows: (1) The benzyl compound is loaded into a reactor and oxygen or air is introduced to form a reaction system. The reaction system is irradiated with a light source containing ultraviolet light, and the reaction temperature is controlled at 20-60°C. The reaction time is at least 10 minutes. After the reaction is completed, an organic liquid containing H2O2 is obtained; (2) The organic liquid containing H2O2 obtained in step (1) is extracted with water as the extractant at the reaction temperature or room temperature. The H2O2 aqueous solution is obtained by phase separation. The above method can not only improve the synthesis rate and economy of H2O2, but also reduce energy consumption and production costs, eliminate safety hazards, and facilitate industrialization.

A multifunctional vinylbenzyl compound is obtained by a reaction between a compound having an aromatic condensed ring, a compound having a biphenylene group, and a compound having a vinylbenzyl group. Further, a resin composition, a prepreg, a resin film, a metal-clad laminate, a printed wiring board, and a semiconductor package are obtained using the multifunctional vinylbenzyl compound.
