the two reactions above, show routes for conversion of an alkene into an oxirane. if the starting alkene is cis-1,2-diphenylethylene the configurations of the oxirane products, a and b are

Respuesta :

Cis; no, product A Product B: no cis Alkenes can be converted to oxiranes via two common processes: Reaction with peroxyacids and Halohydrin formation followed by base reaction

In response to peroxyacids (a) Stereochemistry

The result has the same stereochemistry as the alkene since the reaction with a peroxyacid is a syn addition. The final product is cis-2,3-diethyloxirane because the initial alkene is cis.

Configuration

The product possesses an internal plane of symmetry, which makes it optically inactive. The polarized light plane won't rotate as a result.

A stereochemical analysis

A cyclic halonium ion is used to carry out the process of halogenating the alkene. A cis alkene produces a cis epoxide because the backside displacement of the halide ion by the alkoxide is also stereospecific.

Cis-2,3-diethyloxirane is the item.
