A novel family of indole-amide-based phosphine ligands was designed and synthesized. The Pd/InAm-phos (L1) catalytic system exhibited excellent efficiency in the Suzuki-Miyaura cross-coupling of sterically hindered (hetero)aryl chlorides to synthesize tri-ortho-substituted biaryls. Excellent product yields were obtained in a short reaction time (e.g., 10 min), and a Pd catalyst loading down to 50 ppm was also achieved. The oxidative addition adduct of Pd-L1 with 2-chlorotoluene was also well-characterized by single-crystal X-ray crystallography and showed a κ2-P,O-coordination of L1 with palladium.

experimental part, p. 1175 - 1180 (2012/06/04)
Various N,N-dimethyl aromatic amides were obtained in good to moderate yields by the reaction of aromatic aldehydes with aqueous dimethylamine in the presence of molecular iodine or 1,3-diiodo-5,5-dimethylhydantoin (DIH) at room temperature. Under the same conditions and using the same procedure, treatment of aromatic aldehydes and morpholine in the presence of DIH also provided the corresponding N-aroyl morpholines in good to moderate yields.

The reactions of the anions derived from dithioacetals 1-3 and α-amino nitriles 4 toward pyridinium salts 5 are studied.Depending on the nucleophile used, 2-(dihydropyridylmethyl)indoles 6 and 7, which can be cyclized to tetracyclic methanoazocinindole systems 10 and 11, respectively, or 2-substituted 3-(dihydropyridyl)indoles 8 and 9 are formed.
