Tangentially coupled π systems and their through-space interaction - Trichromophoric perylene dyes

Three perylene tetracarboxylic bisimide chromophores have been attached to a benzene ring in m-position (3). In this way steric and through-bond interactions of the chromophores are minimized and their through-space-interactions can be studied for which a

Chromium-catalysed efficient: N -formylation of amines with a recyclable polyoxometalate-supported green catalyst

A simple and efficient protocol for the formylation of amines with formic acid, catalyzed by a polyoxometalate-based chromium catalyst, is described. Notably, this method shows excellent activity and chemoselectivity for the formylation of primary amines; diamines have also been successfully employed. Importantly, the chromium catalyst is potentially non-toxic, environmentally benign and safer than the widely used high valence chromium catalysts such as CrO3 and K2Cr2O7. The catalyst can be recycled several times with a negligible impact on activity. Finally, a plausible mechanism is provided based on the observation of intermediate and control experiments.

NON-COORDINATING ANION TYPE ACTIVATORS FOR USE WITH POLYOLEFIN POLYMERIZATION CATALYSTS

The present disclosure is related to activator compounds represented by: [Ar(E11R11R22H)xx(E22R33R44)yy][QR55R66R77R88]zz In the formula Ar is a C66-C3030 aromatic hydrocarbyl group, provided that if Ar is a multicyclic ring, then each E11 and each E22 are substitutions on a single ring. Also, x is 1 to 4; y is 0 to 3; z = x; and x+y is 2 to 6. Each of E11 and E22 are independently selected from nitrogen or phosphorous and Q is selected from group 13 of the Periodic Table of the Elements. Additionally, each of R11, R22, R33 and R44 are independently selected from C11-C4040 aliphatic hydrocarbyl, substituted C11-C4040 aliphatic hydrocarbyl and each of R55, R66, R77, and R88 is independently a C66-C2424 hydrocarbyl or a C66-C2424 substituted hydrocarbyl. The present disclosure also relates to catalyst systems including a catalyst and the activator compound. Also, the present disclosure relates to methods of polymerizing olefins.

An efficient way for the: N -formylation of amines by inorganic-ligand supported iron catalysis

The first example of an inorganic-ligand supported iron(iii) catalysed coupling of formic acid and amines to form formamides is reported. The pure inorganic catalyst (NH4)3[FeMo6O18(OH)6] (1), which consists of a central FeIII single-atomic core supported within a cycle-shaped inorganic ligand consisting of six MoVIO6 octahedra, shows excellent activity and selectivity, and avoids the use of complicated/commercially unavailable organic ligands. Various primary amines and secondary amines have been successfully transformed into the corresponding formamides under mild conditions, and the formylation of primary diamines has also been achieved for the first time. The Fe catalyst 1 can be reused several times without appreciable loss of activity.

Co3O4 nanoparticles prepared by oxidative precipitation method: an efficient and reusable heterogeneous catalyst for N-formylation of amines

Abstract: N-formylation of different amines was carried out with formic acid in the presence of the Co3O4 nanoparticles as an efficient, stable heterogeneous catalyst to give the corresponding formamides under solvent-free conditions. This method has advantages over the reported methods such as high yields, mild conditions, easy work-up and short reaction times. The catalyst was characterized by different techniques such as XRD, SEM and FT-IR spectroscopy. Graphical Abstract: [Figure not available: see fulltext.]

Formylation of amines and alcohols using aminopropylated mesoporous SBA-15 silica (APMS) as an efficient and recyclable catalyst

Aminopropylated mesoporous SBA-15 silica (APMS) is introduced as a new, recyclable and efficient catalyst for the formylation of a variety of amines and alcohols by using readily available formic acid under solvent-free conditions.

Acid-induced conformational alteration of cis-preferential aromatic amides bearing N-methyl-N-(2-pyridyl) moiety

A series of cis-preferential aromatic N-methyl amides was designed and synthesized, and acid-induced conformational alteration of these compounds was investigated by means of NMR measurements in solution and X-ray crystal structure analysis. Compounds with a terminal N-methyl-N-(2-pyridyl) amide unit showed acid-induced conformational change from cis to trans, while those with a terminal N-methyl-2-pyridinecarboxamide unit showed a change of the carbonyl orientation from anti to syn with retention of cis conformation.

The above compounds are effective herbicides, particularly for the control of grasses and broadleaf plants with both pre-emergence and post-emergence activity.
