Schulenberg, Nikola,Wadepohl, Hubert,Himmel, Hans-Joerg
, p. 10444 - 10447 (2011)
The answer to an old question: A doubly base-stabilized B3H 6+ analogue (see structure: B green, C gray, N blue, H light gray, H on C not shown) has been synthesized and completely characterized. Quantum-chemical calculations on a simplified model confirmed the presence of closed B-B-B three-center bonding and σ-aromatic character. Copyright
Regio- and Stereoselective Cross-aldol Reactions via Dialkylboryl Triflates
Inoue, Tan,Mukaiyama, Teruaki
, p. 174 - 178 (2007/10/02)
New borylating reagents, (Bu2BOTf and 9-BBNOTf), were prepared in high yields.The triflates reacted with enolizable ketones in the presence of tertiary amines to generate selectively one of the regioisomers of vinyloxyboranes by the choice of the reagents (the dialkylboryl triflates and tertiary amines) under mild reaction conditions.Vinyloxyboranes thus generated showed remarkable reactivity toward aldehydes to give only one regioisomer of the corresponding cross-aldols in good yields.High stereoselectivity was also observed in these reactions.
