Silylation of 1-alkynes with chlorosilanes promoted by zinc: Preparation of alkynylsilanes in a single step

Highly Heat and Oxidation-Resistant Materials Prepared Using Silicon-Containing Thermosetting Polymers with [Si(H)~C≡C] Units

“…Other preparation routes, adaptable to MSP synthesis, such as Grignard addition reactions using chlorosilanes [4,15,16] and dehydrogenative cross-coupling reaction between phenylsilane and m-diethynylbenzene in the presence of some transition metal complexes [5,6,[17][18][19][20][21][22], were also examined. Other routes were not industrially viable and could not yield pure and stable polymers.…”

Synthesis of Two Naturally Occurring 4-Hydroxylated Butenolides with PTP1B Inhibitory Activity

“…Treatment of methyl 10-undecenoate (3) with 9-BBN yielded borane (4), which was further coupled with allyl bromide to afford methyl pentadec-14-enoate (5) in the presence of catalytic amount of [Pd 2 (dba) 3 ]/Cy 3 P (Scheme 1). 2 The ω-alkenylated ester 5 was then coverted into the corresponding acetylenic ester (6) by bromination and subsequent dehydrobromination with the aid of ethanolic potassium hydroxide under reflux.…”

Star‐shaped silicon‐containing arylacetylene resin based on a one‐pot synthesis using zinc powder catalysis with improved processing and thermal properties

“…In addition, the synthetic process of these two methods is tedious with multiple steps. Recently, several other methods have been developed, such as metallic Zn or zinc salt mediated and Zn (OTf) 2 ‐catalyzed reactions between alkynes and chlorosilane . Specifically, for the sake of improving the processability of the PSA resins and simplifying the synthetic process, Shen et al .…”
