Synthesis of 1,1-bis(silyl)-1-alkene derivatives bearing Si–H functional groups via Peterson protocol

Facile route to synthesis of functionalised poly(methylalkoxy)siloxane under mild and aerobic conditions in the presence of platinum catalysts

“…As a part of our continuing research on the organosilicon chemistry [19][20][21][22][23][24], we have particularly been interested in developing the alcoholysis reaction between PMHS and various simple and functional alcohols. The objective of this research is the preparation of novel and functional poly(methylalkoxysiloxane) in mild conditions and high yield approach in the presence of Speier's and Karstedt's catalyst.…”

Synthesis of Novel Organosilicon Compounds Possessing Fully Substituted Imidazole Nucleus Sonocatalyzed by Fe-Cu/ZSM-5 Bimetallic Oxides

“…We have recently reported the preparation and reaction of some compounds bearing organosilicon moieties . [4][5][6][7]21,22] Now we were interested in extending these organosilicon groups in biological important heterocyclic compounds with imidazole core. Therefore, we investigated the synthesis of imidazoles bearing bulky organosilicon groups in the lateral side chain with ether bond.…”

“…[2,3] In recent years organosilicon compounds containing bulky ligands such as (HMe 2 Si) 3 C or (Me 3 Si) 3 C, attached to metals or metalloid, have been widely used which led to synthesis of stable compounds in novel chemistry. [4][5][6][7] Multicomponent reactions are powerful tools in modern drug discovery processes, because they are an important source of molecular diversity, allowing rapid, automated and high throughput generation of organic compounds. [8] Imidazole scaffold-containing derivatives have known to be an important five-membered nitrogen-containing heterocycles with extensive application in many fields such as agrochemical as herbicide, fungicide, and also as ionic liquids, anion sensors, electrical and optical materials, and photosensitive compounds in photography.…”

Synthesis of novel calix[4]arenes containing organosilicon groups

“…By using the Peterson olefination reaction, synthetically useful 2,2-bis(organosilyl)ethenyl groups can be prepared by the reaction of tri(organosilyl)methylmetals with non-enolizable aromatic aldehydes using a direct addition-elimination process [17,27,28]. The starting point for the synthesis of calixarenes containing 2,2-bis(organosilyl)ethenyl groups was the preparation of 5, 17-diformyl-25,26,27,28-tetrapropoxycalix [4]arene 2, which was obtained in 75% yield according to Scheme 2 [29].…”

“…Their use as precursors for the preparation of ketones, as well as variety of organosilicon intermediates such as acylsilanes, epoxysilanes, 1-halovinylsilanes, silylenolethers, (E)-alkenylsilanes, and silylenolacetates, stimulates interest in their synthetic availability [9][10][11][12][13][14][15][16][17]. Therefore, the preparation of calixarenes containing the organosilylvinyl substituents is important.…”
