We report a new air-stable PdI dimer, [Pd(μ-I)(PCy2tBu)]2, which triggers E-selective olefin migration to enamides and styrene derivatives in the presence of multiple functional groups and with complete tolerance of air. The same dimer also triggers extremely rapid C?C coupling (alkylation and arylation) at room temperature in a modular and triply selective fashion of aromatic C?Br, C?OTf/OFs, and C?Cl bonds in poly(pseudo)halogenated arenes, displaying superior activity over previous PdI dimer generations for substrates that bear substituents ortho to C?OTf.

A simple and efficient synthesis of N-vinyl enamides via the lithiation and ring-opening reaction of 2-phenyl-2-oxazolines with lithium diisopropylamide at room temperature has been developed. This method is especially suitable for the synthesis of multif

Various N-acyl-N-alkyl-l-amino-alkenes and -1,3-dienes have been efficiently prepared by reacting aldehydes or ketones 3 with N-alkyl-N-(diphenylphosphinoyl)methyl and -N-(diethoxyphosphoryl)methyl carboxamides 1, 2.
ETUDE COMPARATIVE DE LA PHOTOREACTIVITE D'ENAMIDES ET DE THIOENAMIDS AROMATIQUES TERTIAIRES

Photolytic reactions of some simple aromatic enamides and thioenamides illustrate a novel example of the dramatic difference in the photochemical behaviour of carbonyl and thiocarbonyl compounds.In contrast with their oxo-analogues which are photoconverted into enaminoketones, thioenamides undergo photochemical cyclization to yield isoquinolinethione derivatives which can be easily convered into isoquinolones and tetrahydroisoquinolines.
