Synthesis of fluorescent poly(silyl indole)s via borane-catalyzed C–H silylation of indoles

Abstract

The development of new polymerization strategy is essentially important for design and synthesis of polymers with new framework, since it would effectively expand the structures and properties of polymers. Here...

Tandem Synthesis of Linear Hydridopolycarbosilanes and Postfunctionalization by a Calcium Catalyst

“…Catalytic hydrosilylation of hydrosilanes and olefins to form Si−C bonds is one such reaction and has been well studied with a variety of catalysts, 8−10 including lanthanide, 23,58−67 actinide, 68,69 and transition-metal [11][12][13][14][15][16][17][18]20,70,71 and main group-metal complexes. 72,73 Thus, the precise stoichiometry reactions between hydrosilanes and olefins catalyzed by complex 1 were examined first. As shown in Table high selectivity 49,50,74 in the presence of heavy alkaline-earth metal hydrides.…”

“…A reaction that can form element–element bonds with extremely high conversion and high specificity is a prerequisite for the synthesis of polymers with high molecular weights by the step-growth polyaddition approach. Catalytic hydrosilylation of hydrosilanes and olefins to form Si–C bonds is one such reaction and has been well studied with a variety of catalysts, − including lanthanide, ,− actinide, , and transition-metal − ,,, and main group-metal complexes. , Thus, the precise stoichiometry reactions between hydrosilanes and olefins catalyzed by complex 1 were examined first. As shown in Table , aliphatic olefin (1-hexene) is regioselectively hydrosilylated to give anti-Markovnikov products (Table , runs 1 and 2, see Figure S26 in Supporting Information (SI)).…”

Photocatalytic Metal‐Free Radical Hydrosilylation for Polymer Functionalization†

“…Simply synthesizing functional polymers has attracted increasing attention, [ 1‐7 ] and one of the most effective ways is to functionalize unsaturated polymers by hydrosilylation. [ 2 ] Silane‐ functionalized polymers have potential applications in adhesives, rubbers, drug delivery agents, etc .…”

Expanding the horizons of covalent organic frameworks: sub-stoichiometric synthesis as an emerging toolkit for functional COFs

“…[49][50][51][52] The eld has also witnessed the utilization of unreacted sites, the introduction of noninterfering functional groups, and post-synthetic modications that functionalize the pores or transform the linkages. 30,33,53 The functional versatility of such framework materials has led to various applications, including gas adsorption/separation, [54][55][56][57] host-guest chemistry, 58-61 sensing, [62][63][64][65][66][67][68] ion capture/transport, 69 catalysis, [70][71][72][73][74][75][76] and electrochemical applications. 77 Focussed research activities on COFs that started with the rst report via the formation of dynamic boroxine and boronate ester bonds have now been extended to seeded growth of 2D COFs, graphene nanoribbon 2D COFs, and recently to water harvesting frameworks.…”
