766-77-8 Usage

Chemical Properties

Clear colorless liquid

Physical properties

bp 157 °C/744 mmHg; d 0.889 g cm?3.

Uses

Different sources of media describe the Uses of 766-77-8 differently. You can refer to the following data:
1. Diastereoselective Reduction of Carbonyl Compounds. Hydrosilylation. With a transition metal catalyst, the hydrosilane adds to carbon–carbon double or triple bonds to give alkylsilanes or alkenylsilanes. Hydrosilylating reagent; reductant in combination with acid or F?).
2. Dimethylphenylsilane is a reagent for enol ether synthesis. It acts as a catalyst. Also used as a precursor in Optical Emission Spectroscopy of Plasma Deposition Processes. It can react with vinylbenzene to produce (b-Phenyl-ethyl)-dimethylphenyl-silan.
3. Reagent for enol ether synthesis.

Application

Used to reduce α-amino ketones to aminoethanols withhigh stereoselectivity. Used in the fluoride ion-catalyzedreduction of aldehydes and ketones, and α-substitutedalkanones to threo products. Erythro reduction of α-substituted alkanones to diols and aminoethanols. Together with CuCl reduces aryl ketones, but not dialkylketones. Used in the silylformylation of acetylenes.Excellent reducing agent for the reduction of enones tosaturated ketones. Shows better selectivity than LAH inthe reduction of oximes to alkoxyamines.

Check Digit Verification of cas no

The CAS Registry Mumber 766-77-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 766-77:
(5*7)+(4*6)+(3*6)+(2*7)+(1*7)=98
98 % 10 = 8
So 766-77-8 is a valid CAS Registry Number.

Platinum Catalysed Regioselective ortho-Silylation of Benzylideneamines via Intramolecular C-H Activation

Williams, Neil A.,Uchimaru, Yuko,Tanaka, Masato

, p. 1129 - 1130 (1995)

The Pt-P(OCH2)3CEt complex catalyses the ortho-silylation of benzylideneamines with disilanes via intramolecular C-H activation; both mono- and bis-silylated products are obtained.

Hydrogenolysis of Polysilanes Catalyzed by Low-Valent Nickel Complexes

Comas-Vives, Aleix,Eiler, Frederik,Grützmacher, Hansj?rg,Pribanic, Bruno,Trincado, Monica,Vogt, Matthias

supporting information, p. 15603 - 15609 (2020/04/29)

The dehydrogenation of organosilanes (RxSiH4?x) under the formation of Si?Si bonds is an intensively investigated process leading to oligo- or polysilanes. The reverse reaction is little studied. To date, the hydrogenolysis of Si?Si bonds requires very harsh conditions and is very unselective, leading to multiple side products. Herein, we describe a new catalytic hydrogenation of oligo- and polysilanes that is highly selective and proceeds under mild conditions. New low-valent nickel hydride complexes are used as catalysts and secondary silanes, RR′SiH2, are obtained as products in high purity.

Catalytic Reduction of Alkoxysilanes with Borane Using a Metallocene-Type Yttrium Complex

Aoyagi, Keiya,Matsumoto, Kazuhiro,Shimada, Shigeru,Sato, Kazuhiko,Nakajima, Yumiko

supporting information, p. 210 - 212 (2019/02/01)

The catalytic reduction of alkoxysilanes with the borane HBpin (pin = pinacolato) was achieved using a metallocene-type yttrium complex as a catalyst precursor. Mechanistic study supported the pivotal role of the rigid metallocene structure of the catalyst, which bears two bulky n5-C5Me4SiMe3 ligands, in suppressing the coordination of the side product MeOBpin that is generated during the reaction.
