52885-14-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52885-14-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,8,8 and 5 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 52885-14:
140 % 10 = 0
So 52885-14-0 is a valid CAS Registry Number.

Catalysis of hydrosilylation: Part XXXIV. High catalytic efficiency of the nickel equivalent of Karstedt catalyst [{Ni(η-CH2=CHSiMe2)2O} 2{μ-(η-CH2=CHSiMe2)2O}]


, p. 175 - 181 (2007/10/03)

The nickel equivalent of Karstedt catalyst [{Ni(η-CH2=CHSiMe2)2O} 2{μ-(η-CH2=CHSiMe2)2O}] (1) appeared to be a very efficient catalyst for dehydrogenative coupling of vinyl derivatives (styrene, vinylsilanes, vinylsiloxanes) with trisubstituted silanes HSi(OEt)3, HSiMe2Ph. The reaction occurs via three pathways of dehydrogenative coupling, involving formation of an unsaturated compound as the main product as well as a hydrogenated olefin (DS-1) pathway, hydrogenated dimeric olefin (DS-2) and dihydrogen (DC), respectively. The reaction is accompanied by side hydrosilylation. Stoichiometric reactions of 1 with styrene and triethoxysilane, in particular synthesis of the bis(triethoxysilyl) (divinyltetramethyldisiloxane) nickel complex 3 and the first documented insertion of olefin (styrene) into Ni-Si bond of complex 3, as well as all catalytic data have allowed us to propose a scheme of catalysis of this complex reaction by 1.

Catalysis of hydrosilylation. Part XXV. Effect of nickel(0) and nickel(II) complex catalysts on dehydrogenative silylation, hydrosilylation and dimerization of vinyltriethoxysilane

, p. 147 - 152 (2007/10/02)

General catalysis by Ni(O) and Ni(II) phosphine and non-phosphine complexes of the competitive-consecutive reaction of vinyltriethoxysilane with triethoxysilane has been observed to give mainly products of dehydrogenative silylation and hydrogenative dimerization accompanied by products of regular hydrosilylation, disproportionation of substrates and secondary reactions of the product-bis(silyl)ethene.In an excess of vinylsilane, side reactions can be practically eliminated.Tertiary phosphine and phosphite ligands of nickel acetylacetonate (Ni(acac)2*2PR3) stop the consecutive reactions of bis(silyl)ethene but in the presence of ?-basic and bulky tricyclohexylphosphine the system catalyzes selectively the regular hydrosilylation of bis(silyl)ethene.Keywords: Nickel; Silicon; Hydrosilylation; Silane; Catalysis

Catalysis of hydrosilylation. XX. Unusual reaction of vinyltriethoxysilane with triethoxysilane catalyzed by nickel acetylacetonate

Marciniec, Bogdan,Maciejewski, Hieronim,Mirecki, Janusz

, p. 61 - 67 (2007/10/02)

Nickel acetylacetonate is shown to be a catalyst of an unusual reaction of vinyltriethoxysilane with triethoxysilane involving formation of bis(silyl)ethene and bis(silyl)butanes as the main products accompanied by others of direct and dehydrogenative hydrosilylation, bis(silyl)ethane and ethylsilane as well as products of redistribution of triethoxysilane and formation of oligomers.The latter reaction is a consequence of consecutive oligomerization of bis(silyl)ethenes and other products.The effect of temperature, the concentration ratio of substrates and the catalyst, and other reaction conditions on the conversion and reaction yield led us to propose a scheme explaining the course of this competitive-consecutive reaction.
