Phenylselenenyl chloride Usage And Synthesis

Chemical Properties

crystalline solid

Uses

Phenylselenenyl chloride is used in the preparation of (cyclobut-1-enylselanyl)benzene. It is an important versatile reagent used in organic synthesis. Further, it serves as a useful synthon for 2-amino alcohols.

Application

Phenylselenenyl chloride as a reagent for the facile preparation of cyclic ethers from diolefins[1].

General Description

Phenylselenyl chloride is a synthon for 2-amino alcohols. It is a versatile reagent in organic synthesis.

Purification Methods

Purify it by distillation in a vacuum, and recrystallisation (orange needles) from hexane [Foster J Am Chem Soc 55 822 1933, Foster et al. Recl Trav Chim, Pays-Bas 53 405, 408 1934, Behaghel & Seibert Chem Ber 66 714 1933]. [Beilstein 6 III 1110.] HIGHLY TOXIC.
