An iodine-promoted, metal-, base-, and solvent-free cross-couplingreaction was developed for the synthesis of various useful secondary amides via an aryl N-addition reaction of aryl groups to cyano groups. This aryl transfer reaction proceeds with arylhydrazine hydrochlorides serving as the aryl donors. A labelling experiment shows that the N atom in the product comes from the cyano group of the nitriles

nitriles to N-phenyl amides has been achieved through a novel intermolecular phenyl transfer reaction from phenyl hydrazides and N-addition to nitriles in the presence of PIFA under mild and solvent-free conditions. This cross-coupling reaction includes the oxidative cleavage of sp2 C–N bonds of phenyl hydrazides to form a phenyl radical and the subsequent N-addition to cyanos to form new sp2 C–N bonds

We disclose the first small molecule histone deacetylase (HDAC) inhibitor (3, BRD73954) capable of potently and selectively inhibiting both HDAC6 and HDAC8 despite the fact that these isoforms belong to distinct phylogenetic classes within the HDAC family of enzymes. Our data demonstrate that meta substituents of phenyl hydroxamic acids are readily accommodated upon binding to HDAC6 and, furthermore, are necessary for the potent inhibition of HDAC8.
