C-H activations on a 1H-1,4-benzodiazepin-2(3H)-one template

Air stable benzodiazepine containing palladacycles were synthesized by a C-H activation reaction and studied by mass spectrometry and X-ray crystallography. Catalytic C-H functionalizations of 1-methyl-5-phenyl-1H-1,4-benzodiazepin-2(3H)-one with diphenyliodonium hexafluorophosphate led to a mixture, which included the starting material and the expected product 1-methyl-5-(2'-biphenyl)-1H-1,4-benzodiazepin-2(3H)-one.

Organometallic pincer-type complexes: recent applications in synthesis and catalysis

YCY pincer palladacycles, where YCY is typically an SCS, NCN, PCP, SeCSe anionic six-electron donor ligand (e.g. see 1-6, Scheme 1.1), are a well-established family of organometallic complexes with manifold applications in catalysis, synthesis and materials science [1-24]. Their synthesis can be achieved by many routes including C-H activation, oxidative addition, transmetalation and trans-cyclopalladation [25].
