Room-Temperature Negishi Reaction of Trisubstituted Vinyl Phosphates for the Synthesis of Tetrasubstituted Alkenes

, p. 10728 - 10739 (2020)
The present study investigated the ability of bromovinyl phosphates to react with organozinc reagents at room temperature during palladium-catalyzed reactions. It was determined that both the bromine atom and the phosphate group were successfully substituted by means of the reaction with the organozinc reagents, thereby allowing for the synthesis of cyclic and acyclic tetrasubstituted double bonds. The low stability of the organozinc compounds in an acidic environment was exploited to accomplish the synthesis of alkenes using a one-pot, two-step experimental setup.

Special aromatic structure and unique geometric characteristics make subphthalocyanines possess distinctive electronic structures and physicochemical properties. In this paper, tetraarylethylenes with aggregation-induced emission were introduced to subphthalocyanine macrocycles at the axial direction and the periphery to improve the fluorescence emission properties. Results show that the modification at the two different positions of the subphthalocyanines has different effects on regulating the fluorescence performances. The subphthalocyanine modified axially by tetraphenylethylene shows outstanding fluorescence resonance energy transfer (FRET) phenomenon, and the modification on the periphery of subphthalocyanine is conducive to enhance the fluorescence intensity. These distinctive performances have the potential applications in fluorescence sensor and probe.

Tetraarylethenes are obtained by acid-induced coupling of vinyl triazenes with aromatic compounds. This new C?H activation route for the synthesis of aggregation-induced emission luminogens is simple, fast, and versatile. It allows the direct grafting of triarylethenyl groups onto a variety of aromatic compounds, including heterocycles, supramolecular hosts, biologically relevant molecules, and commercial polymers.

Fluorescent polymersomes with both aggregation-induced emission (AIE) and CO2-responsive properties were developed from amphiphilic block copolymer PEG-b-P(DEAEMA-co-TPEMA) in which the hydrophobic block was a copolymer made of tetraphenylethene functionalized methacrylate (TPEMA) and 2-(diethylamino)ethyl methacrylate (DEAEMA) with unspecified sequence arrangement. Four block copolymers with different DEAEMA/TPEMA and hydrophilic/hydrophobic ratios were synthesized, and bright AIE polymersomes were prepared by nanoprecipitation in THF/water and dioxane/water systems. Polymersomes of PEG45-b-P(DEAEMA36-co-TPEMA6) were chosen to study the CO2-responsive property. Upon CO2 bubbling vesicles transformed to small spherical micelles, and upon Ar bubbling micelles returned to vesicles with the presence of a few intermediate morphologies. These polymersomes might have promising applications as sensors, nanoreactors, or controlled release systems.
