Highly regio- and stereoselective ring-opening of epoxides and aziridines with sodium azide using ammonium-12-molybdophosphate

Cycloheptyl-fused N,N,N′-chromium catalysts with selectivity for vinyl-terminated polyethylene waxes: thermal optimization and polymer functionalization

Narrowly dispersed linear polyethylenes containing high levels of vinyl end-groups are accessible using cycloheptyl-fused Cr-catalysts operating at high temperature.

Facile synthesis of chain end functionalized polyethylenes via epoxide ring-opening and thiol–ene addition click chemistry

A library of low MW chain end functionalized polyethylenes with narrow MW distributions were prepared under mild conditions.

1,1'-Bis-Methyl-3, 3-Methylenebisimidazolium Dichloride as an Efficient Phase Transfer Catalyst for Ring Opening of Epoxides Using SCN- and N3- in water

An efficient synthesis of β-azido alcohols and β-hydroxy thiocyanates has been achieved by ring opening of epoxides using 1,1'-bis-methyl-3, 3-methylene-bisimidazolium dichloride as a phase transfer catalyst at room temperature in water. The reaction is regioselective and afforded the corresponding products in moderate to excellent yields.

Ethyl 3-(2-chloro-5,8-dimethoxyquinolin-3-yl)-2-cyanooxirane-2-carboxylate

The title mol­ecule, C₁₇H₁₅ClN₂O₅, contains a quinolyl unit linked to a functionalized oxirane system with a 2,3-trans arrangement of the substituents (ester group versus quinol­yl). The structure can be described as being built up from zigzag layers parallel to (10). The heterocyclic ring of the quinolyl unit forms a dihedral angle of 60.05 (1)° with the oxirane plane. The crystal packing is stabilized by inter­molecular C—H⋯O and C—H⋯N hydrogen bonding, resulting in the formation of an infinite three-dimensional network and reinforcing the cohesion between the layers.
