Abstract: PURPOSE:To readily obtain a 2-amino-alcohol in good yield by reacting a 1- aza-2-silacyclobutane compound with an alcohol and then oxidatively desilylating the resultant product. CONSTITUTION:A 1-aza-2-silacyclobutane compound expressed by formula I (R<1> to R<5> are H or hydrocarbon group; R<6> is hydrocarbon group; R<7> is H or organic group) is reacted with an alcohol in the presence of a protonic acid (e.g. ammonium chloride) to provide a silylamino compound expressed by formula II (R<6> is alcohol residue). Normal desilylating reaction is then carried out in the coexistence of an alkaline substance or fluoride ions in an organic solvent using an oxidizing agent (e.g. hydrogen peroxide) as ambient temperature to afford the objective substance expressed by formula III.

When cutting off a light, the photoelectromotive force applied to the gate of the FET4 becomes zero, therefore, the FET4 becomes an on-state, and a charge of a capacitor 2 can be discharged quickly. The depression type FET shows a higher resistance than a simple resistor in case of a voltage V1 of the time of photodetecting, becomes a low resistance in case of a voltage V2 of the time when cutting off a light, which is lower than said voltage, and can make a discharge current flow in large quantities.
