<i>N</i>-Heterocyclic Carbene-Borane Adducts with Chiral (<i>R</i>)-Chloroethyl and Vinyl Substituents.

ABSTRACT: This research provides how chiral imidazolium salts {1,3-bis[1'-chloro-1'-phenylpropan-2'-yl]-imidazolium} (1a) and enantiopure {1,3-bis[(R)-1-chlorobutan-2-yl]-imidazolium} [1b] can be utilized in diverse synthetic pathways to obtain new carbene-borane adducts (2a-2d): {1,3-bis[1'-chloro-1'-phenylpropan-2'-yl]-imidazolyl-2-ylidene-borane} (2a), {1,3-bis[(Z)-1'-phenylpropen-2'-yl]-imidazolyl-2-ylidene-borane} (2b), {1,3-bis[(R)-1-chlorobutan-2-yl]-imidazolyl-2-ylidene-borane} (2c), and {1,3-bis[but-1-en-2-yl]-imidazolyl-2-ylidene-borane} (2d). The carbene-borane adducts were synthesized and characterized by ¹³C, ¹H, and ¹¹B nuclear magnetic resonance spectroscopy and time-of-flight
