Protocols to effect β-arylation of sp3 C–Hbonds via Pd(II)/(IV) and Pd(0)/(II) catalytic cycles have been achieved using a newly developed monodentate CONHC6F5 directing group. These reactions provide an unprecedented means to functionalize sp3 C–Hbonds in aliphatic carboxylic acid-derived substrates.

αβ-Olefinicamides with various substitution patterns at the carbon–carbon double bond and at nitrogen are all reduced to the corresponding saturated amides by magnesium and methanol. The same reducing system reduces N-benzyl-8-azabicyclo[4.3.0]nona-1(6),3-dien-7-ones at the conjugated double bond to give mixtures of the cis-and trans-dihydro-derivatives; the isolated, non-conjugated double bond is
在碳-碳双键和氮上具有各种取代方式的αβ-烯烃酰胺都被镁和甲醇还原为相应的饱和酰胺。相同的还原体系将共轭双键处的N-苄基-8-氮杂双环[4.3.0] nona-1(6),3-dien-7-还原为顺式和反式二氢衍生物的混合物。分离的非共轭双键即使在3,4-二苯基取代的化合物中也不会还原。镁和甲醇降低喹啉-2(1 H ^) -酮其3,4-二氢衍生物,和5,6,7,8-四氢喹啉-2(1 H ^) -酮于两个二氢衍生物的混合物。

The carbon-carbon double bond in αβ-olefinicamides can be selectively reduced by magnesium and methanol; other olefinic bonds, including those of the stilbene type are unaffected.

ligand-free conditions, namely, hydroaminocarbonylation of olefins, aminocarbonylation of aryliodides and oxidative carbonylation of amines, which almost cover all the known mechanisms in carbonylation reactions. Notably, the bulk Pdcatalyst system exhibited better catalytic activity than the classical homogeneous PdCl2/(2-OMePh)3P catalyst system. This study will create a momentous and new field of green
