Abstract
We describe a palladium-catalyzed Suzuki-type cross-coupling reaction of 2-pyridyl carbamoyl fluorides with boronic acids, which provides entry to medicinally relevant pyridyl amides. Mechanistic studies, including the synthesis and reactivity of carbamoyl Pd-F complexes, reveal the importance of both the fluoride electrophile and nitrogen directing group for aiding reactivity.

Abstract
Enantiomerically enriched allyl halides are rare due to their configurational lability. Stable piperidine-based allyl chloride enantiomers can be produced via kinetic resolution, and undergo highly enantiospecific catalyst-free substitutions.

Abstract
An efficient route to construct 2,5-disubstituted tetrazole hemiaminal silyl ethers via one-pot three-component hemiaminal silylation of 5-substituted tetrazoles, aldehydes, and silyl triflates was developed. Diverse 2,5-disubstituted tetrazole hemiaminal silyl ethers were obtained with 37 : 63->99 : 1 regioisomeric ratios. The regioselectivities of this reaction were significantly affected by steric hindrance and the conjugation effects of substitutions on the 5-position of tetrazoles.
