This invention when orutokarubontoriarukiruesuteru (ortho ester O) it produces C1 - C4 - alcohol (alcohol A) , - diketone or , with the electrochemistry oxidation of - hydroxy ketone under existing, to exist in the form of the ketaru functional group where the keto functional group is induced from C1 - C4 - alkyl alcohol exist in the form of the ether functional group where the hydroxyl functional group is induced from C1 - C4 - alkyl alcohol at the same time by when, (ketaru K), in electrolyte ortho ester O and total and alcohol A from of ketaru KIt regards the method mol ratio being the 0.2:1 - the 5:1. Mol ratio with ketaru K in electrolyte and alcohol A is the 0.2:1 - the 10:1.
