The Prilezhaev reaction, in which an alkene and a peroxyacid react to form an epoxide, is named after him.

Prilezhaev was the son of a clergyman and studied chemistry at the Theological Seminary in Warsaw (graduated in 1895) and then at the University of Warsaw under the supervision of Yegor Yegorovich Vagner (Georg Wagner).{{cite book|author=David E.

After earning a master's degree in 1912 in St. Petersburg, he became an associate professor of organic chemistry at the University of Warsaw. In 1915 he became a professor at the Polytechnic in Kiev and 1924 at the University of Minsk. There he established the Faculty of Chemistry and between 1931 and 1933 was director of the Institute of Chemistry of the Belarusian Academy of Sciences.

He dealt mostly with oxidation processes, following in the footsteps of chemists such as Alexei Nikolaevich Bach. For example, he studied reactions between unsaturated compounds and peroxides. He discovered his name reaction in 1908 and continued to study its intermediates and products.

He was a corresponding member of the Soviet Academy of Sciences (1933) and a member of the Belarusian Academy of Sciences (1940). In 1912 he received the Butlerov Prize.
