Dehydrogenative silation, isomerization and the control of syn- vs. anti-addition in the hydrosilation of alkynes
Jun, Chul-Ho,Crabtree, Robert H.
, p. 177 - 187 (1993)
Alkyne hydrosilation has been examined in detail for the catalysts SbF6 (L = PPh3, bq = 7,8-benzoquinolinato) and RhCl(PPh3)3.Factors that favor the normal syn- or the unusual anti-silane addition to the alkynes are examined.Two other unus
Vinylgallium and alkyllithium compounds: Transmetalation and generation of oligolithium cages
Uhl, Werner,Kovert, Dirk,Layh, Marcus,Hepp, Alexander
, p. 13553 - 13561 (2011)
Vinylgallium compounds [C6H6-n{(H)C=C(SiR 2R′)-GaR″2}n] (3, R=Ph, Me; R′=Ph, Me; R″=tBu, Et; n=1, 2) are easily accessible by hydrogallation of the corresponding alkynylbenzene derivatives with H-GaCl
On the reaction of silylperoxides with carbanions
Florio,Troisi
, p. 3141 - 3144 (1993)
Silylperoxides 1a-f react with organolithiums 2,5,9 and 11 giving alkylation products, silylethers or silanes depending upon substitution on the silicon. A hypervalent silicon intermediate is proposed.
Tuning the Selectivity of AuPd Nanoalloys towards Selective Dehydrogenative Alkyne Silylation
Wissing, Maren,Studer, Armido
supporting information, p. 5870 - 5874 (2019/03/21)
The cross-dehydrogenative coupling of terminal alkynes and hydrosilanes catalyzed by AuPd nanoalloys is described. Metal nanoparticles are readily prepared in 15 minutes from commercially available and cheap starting materials by using a photochemical app
Regioselective synthesis of multisubstituted benzenes by palladium-catalyzed intermolecular reaction of β-iodo-β-silylstyrenes with alkynes
Kinoshita, Hidenori,Takahashi, Hirotoshi,Miura, Katsukiyo
supporting information, p. 2962 - 2965 (2013/07/26)
The Pd-catalyzed reaction between β-iodo-β-silylstyrenes and terminal alkynes in i-Pr2NEt gave 1,2,3,5-tetrasubstituted benzenes with complete regioselection. The use of certain silylacetylenes as alkynes enabled efficient synthesis of 1,3,5-trissilyl-2-arylbenzenes, which could be transformed into other multisubstituted benzenes by displacement of the silyl groups.
Dehydrogenative silylation of terminal alkynes with hydrosilanes under zinc-pyridine catalysis
Tsuchimoto, Teruhisa,Fujii, Masakazu,Iketani, Yoshihiko,Sekine, Masaru
supporting information, p. 2959 - 2964 (2013/01/15)
A combination of zinc triflate and pyridine in a nitrile medium was found to act as an effective catalytic system for dehydrogenative silylation with flexible pieces of terminal alkynes and hydrosilanes, thereby producing diverse alkynylsilanes in high to
Copper(I) chloride catalyzed cross-dehydrocoupling reactions between silanes and ethynyl compounds. A new method for the copolymerization of silanes and alkynes
Liu, Hua Qin,Harrod, John F.
, p. 1100 - 1105 (2007/10/02)
In the presence of an amine, copper(I) chloride is an effective catalyst for the cross-dehydrocoupling of silanes with alkynes.The reactions proceed at useful rates above 100 deg C, but rates drop dramatically on going from 1o to 2o
