Unprecedented regioselectivity to the branched aldehyde product in the hydroformylation of propene was attained on embedding a rhodium complex in supramolecular assembly L2, formed by coordination-driven self-assembly of tris(meta-pyridyl)phosphine and zinc(II) porpholactone. The design of cage L2 is based on the ligand-template approach, in which the ligand acts as a template for cage formatio...

Comprehensive Summary The direct use of non‐prefunctionalized arene and alkane as the starting materials to construct C aryl −C alkyl bond is an unfulfilled target approaches this challenge rarely surface in methodology studies. Current methods for thermocatalytic arene‐alkane couplings (AAC) occur with specific substrates and/or inconvenient reagents. Herein, we report a one‐pot relay bicataly...

Abstract A one-step chlorosulfonylation of acrylamides via a photocatalytic redox process is described. This reaction provides α-chlorosulfonylamides with quaternary center high regioselectivity radical process. It amenable to broad range substrates and the products are obtained in moderate good yields.

selective transformation of 2-propargylthio-6-methyl-pyrimidin-4(1h)on e (2) to 3,5-dimethyl-7h-thiazolo [3,2-a] pyrimidin-7-one (3) is performed under the conditionof base catalysis . for elucidation of structure, palladium catalyzed cyclization reaction of (2) was carried out and the structures of the products were assigned (5) and (6). these compounds underwent isomerization to (3) and (4) r...

In this study, β-cyclodextrin(β-CD) supported, hydroxyapatite encapsulated γ-Fe2O3 (γ-Fe2O3@HAp@β-CD) was successfully prepared and evaluated as a solid-liquid phase transfer catalyst and also a molecular host system and nanoreactor for the nucleophilic ring-opening of epoxides in water for the preparation of β-azido alcohols, β-nitro alcohols, an...

In the context of new scaffolds obtained by photochemical reactions, Paternò-Büchi reactions between heteroaromatic, trifluoromethylphenyl ketone and electron rich alkenes to give oxetanes are described. A comprehensive study has then been carried out on reaction aromatic ketones with fluorinated alkenes. Depending substitution pattern at oxetane ring, a metathesis is described as minor side pr...

Epoxide ring-opening is a key reaction in organic chemistry. We have previously shown that B(C6F5)3, strongly Lewis acidic arylborane, exhibited high rates and unusual selectivities for catalyzing the of aliphatic epoxides with alcohols. Here we compare catalysts form B(C6H5?XFX)3 (x = 5, 4, 3, 0) determine moderately arylboranes higher regioselectivity, but slower this reaction. At temperature...
