4,4,5,5-Tetramethyl-2-[(Z)-1-(3-methylphenoxy)hex-1-en-2-yl]-1,3,2-dioxaborolane

Abstract

The title compound, C19H29BO3, was prepared by the reaction of 1-(hex-1-yn-1-yloxy)-3-methylbenzene in tetrahydrofuran with 4,4,5,5-tetramethyl-1,3,2-dioxaborolane under a nitrogen atmosphere. In the molecule, the butyl group adopts an extended conformation, with a torsion angle of 179.52 (19)°. The dioxaborolane ring has a twisted conformation on the C—C bond, and its mean plane is inclined to the 3-methylphenyl ring by 44.79 (19)°. In the crystal, there are no significant intermolecular interactions present.
