A Ru-catalyzed direct arylation of benzylic sp3 carbons of acyclic amines with arylboronates is reported. This highly regioselective and efficient transformation can be performed with various combinations of N-(2-pyridyl) substituted benzylamines and arylboronates. Substitution of the pyridine directing group in the 3-position proved to be crucial in order to achieve high arylation yields. Furthermore, the pyridine directing group can be removed in high yields via a two-step protocol.
Generation of organolithium compounds bearing super silyl ester and their application to Matteson rearrangement

It's super-silyl-fragilithyl-ester-aryl-docious: The super silyl group is a strong protecting group for carboxylic acids and provides a method for direct lithiation that is compatible with the ester moiety. Organolithium compounds bearing a super silyl ester react with a variety of electrophiles in high yields (see scheme). The reaction of lithiated super silyl chloroacetate with a boron compound gives α-functionalization of the ester moiety by Matteson rearrangement. Copyright
Derivatization and Mass Spectrometric Investigation of Substituted Benzeneboronic Acids. The Use of Linked Scanning During Gas Chromatography Mass Spectrometry
Longstaff, Colin,Rose, Malcolm Edward
, p. 508 - 518 (2007/10/02)
Substituted benzeneboronic acids are important intermediates in the synthesis of support matrices for affinity chromatography but their analysis by mass spectrometry is hindered by thermal reactions in the ion source.A simple derivatization with 1,2- or 1
Alkynes as activators in the nickel-catalysed addition of organoboronates to aldehydes
Takahashi, Go,Shirakawa, Eiji,Tsuchimoto, Teruhisa,Kawakami, Yusuke
, p. 1459 - 1461 (2007/10/03)
Alkynes act not as substrates but as co-catalysts in the presence of a nickel catalyst, an organoboronate and an aldehyde to promote the addition reaction between the substrates in combination with H2O. The Royal Society of Chemistry 2005.
