Hydroboration of Substituted Cyclopropane : A Density Functional Theory Study

Abstract EN

The hydroboration of substituted cyclopropanes has been investigated using the B3LYP density functional method employing 6-31G** basis set.

Borane moiety approaching the cyclopropane ring has been reported.

It is shown that the reaction proceeds via a three-centered, “loose” and “tight,” transition states when boron added to the cyclopropane across a bond to a substituents.

Single point calculations at higher levels of theory were also performed at the geometries optimized at the B3LYP level, but only slight changes in the barriers were observed.

Structural parameters for the transition state are also reported.
