LiBF4: A mild and novel reagent for the O-H insertion reactions of α-diazoketones
Yadav,Reddy,Vishnumurthy
, p. 5691 - 5694 (2003)
Lithium tetrafluoroborate (10 mol%) is found to catalyze efficiently the O-H insertion reactions of α-diazoketones with various alcohols including benzylic, allylic, propargylic and cyclopropyl carbinols to produce the corresponding α-alkoxy ketones in excellent yields with high selectivity. A solution of 10 mol% of LiBF4 in acetonitrile provides a convenient reaction medium to carry out the O-H insertion reactions under mild and neutral conditions.

A highly enantioselective NiH-catalyzed hydrocyclization of alkynones with unparalleled anti- and endocyclic selectivities is described. The choice of the precatalysts has significant influence in tuning the regio- and enantioselectivity. Using Ni(OTs)su
Green Protocol for the O-H Insertion of α-Diazoketones with Alcohols and Water Using Ionic Liquid [Bmim]BF4
Yadav,Reddy,Srinivas
, p. 1060 - 1061 (2007/10/03)
α-Diazoketones undergo readily O-H insertion reactions with alcohols and water in hydrophilic [bmim]BF4 ionic liquid in the absence of any acid catalyst to furnish α-alkoxy and α-hydroxy ketones in excellent yields under neutral conditions. The recovered ionic liquid can be easily reused in four to five cycles with consistent in activity. The use of ionic liquid helps to avoid the use of acid catalysts as well as environmentally unfavorable volatile organic solvents.
