International audienceHybrid silica materials containing the di-(2-pyridyl)methylamine-palladium dichloride complex, prepared by sol-gel cogelification, are efficient recyclable catalysts for Suzuki (aryl bromides and chlorides), Heck (aryl bromides) and Sonogashira reactions (aryl iodides and bromides). Formation of palladium(0) nanoparticles is observed in the Suzuki and Heck reactions but not in the Sonogashira coupling

“…Attempts to purify 4 by distillation failed due to decomposition reactions which gave diphenylphosphane as the major phosphorus-containing product. (5) A second phosphanylation according to equation (6) gave N,N-bis(diphenylphosphanyl)-2-pyridylmethylamine (5), even though the steric argument should favour the C-substi- tution. This compound formed also as a minor by-product during the synthesis of 4.…”

“…This compound formed also as a minor by-product during the synthesis of 4. (6) In order to compare these substituted 2-pyridylmethylamines, the molecular structures of [(1)LiCl] 2 is shown in Figure 1. Due to the inversion symmetry of [1·LiCl] 2 the solid state consists of a racemate.…”

The metathesis reaction of lithium 2-pyridylmethylamide with chloroalkanes and phosphanes yields N-and C-substitution products depending on the electrophile. Thus, C-alkylated 1-amino-1-(2-pyridyl)-2,2-dimethylpropane (1) and 1-amino-1-(2-pyridyl)-2phenylethane (2) and N-substituted N-benzyl-(2-pyridylmethyl)amine (3) and N-(diphenylphosphanyl)-2-pyridylmethylamine (4) are obtained. In [1·LiCl] 2 , molecule 1 binds to the lithium atom in a bidentate fashion. C-and N-substituted 2-pyridylmethylamines are compared with quantum chemical methods. Lithiation of 4 and subsequent reaction with cloro-diphenylphosphane yields N,N-bis(diphenylphosphanyl)-2-pyridylmethylamine (5) with a planar amine nitrogen atom. Metallation of 4 with dibutylmagnesium 893 leads to the formation of colorless (tetrahydrofuran)magnesium bis[N-(diphenylphosphanyl)-2-pyridylmethylamide] (6) with a penta-coordinate alkaline earth metal atom in a trigonal bipyramidal environment. In contrast to this observation, the reaction of 4 with dimethylzinc yields colorless methylzinc bis[N-(diphenylphosphanyl)-2-pyridylmethylamide] (7). Zincation of 1 gives dimeric methylzinc 1-(2-pyridyl)-2,2-dimethyl-1-propylamide (8). In these zinc complexes the metal and amide nitrogen atoms are in distorted tetrahedral environments.
