Exploring structural trends for complexes of Me2E(OSO 2CF3)2 (E = Si, Ge, Sn) with pyridine derivatives

The coordination of Me2E(OTf)2 (E = Si, Ge, Sn) acceptors by dmap or 2,2′-bipy furnishes two series of complexes which exhibit distinct structural trends that correlate with the covalent radii of the tetrael elements, and which contrast complexes of these ligands with EX 4 (X = Cl or Br). the Partner Organisations 2014.

Hydrosilane Synthesis by Catalytic Hydrogenolysis of Chlorosilanes and Silyl Triflates

Hydrogenolysis of the chlorosilanes and silyl triflates (triflate = trifluoromethanesulfonate, OTf-) Me3-nSiX1+n (X = Cl, OTf; n = 0, 1) to hydrosilanes at mild conditions (4 bar of H2, room temperature) is reported using low loadings (1 mol %) of the bifunctional catalyst [Ru(H)2CO(HPNPiPr)] (HPNPiPr = HN(CH2CH2P(iPr)2)2). Endergonic chlorosilane hydrogenolysis can be driven by chloride removal, e.g., with NaBArF4 [BArF4- = B(C6H3-3,5-(CF3)2)4-]. Alternatively, conversion to silyl triflates enables facile hydrogenolysis with NEt3 as the base, giving Me3SiH, Me2SiH2, and Me2SiHOTf, respectively, in high yields. An outer-sphere mechanism for silyl triflate hydrogenolysis is supported by density functional theory computations. These protocols provide key steps for synthesis of the valuable hydrochlorosilane Me2SiClH, which can also be directly obtained in yields of over 50% by hydrogenolysis of chlorosilane/silyl triflate mixtures.

Polyfunctionalmonomer compound and preparation method thereof and photosensitive resin composition

The present disclosure relates to a polyfunctional monomer compound and a preparation method thereof and a photosensitive resin composition having the structure represented by a formula (1) shown in the specification. The polyfunctional monomer compound is capable of producing acid in a development process when meeting water to promote development of an unexposed portion; and for an exposed portion, the polyfunctional monomer compound can participate in polymerization, and is crosslinked with other polymerizable components in a photoresist composition into a network structure, the stability ofa resin cured film is not influenced due to acid production, a compound produced after hydrolysis of the polyfunctional monomer compound contains silicon hydroxyl, and adhesion between the resin cured film and a glass substrate can be also increased. At the same time, since the polyfunctional monomer compound itself does not have acidity, the storage stability of the polyfunctional monomer compound is generally improved compared with the storage stability of a color photoresist which generally contains a small molecule acid or acidic substance as a development aid.

Preparation of vinyl silyl ethers and disiloxanes via the silyl-heck reaction of silyl ditriflates

Vinyl silyl ethers and disiloxanes can now be prepared from aryl-substituted alkenes and related substrates using a silyl-Heck reaction. The reaction employs a commercially available catalyst system and mild conditions. This work represents a highly practical means of accessing diverse classes of vinyl silyl ether substrates in an efficient and direct manner with complete regiomeric and geometric selectivity.

Phenylenbis(silandiyl triflates) - New Synthetic Building Blocks for Variously Structured Organosilicon Polymers

Ortho-, meta-, and para-substituted phenylenbis(silandiyl triflates) are prepared as new useful building blocks for the synthesis of polymers with a regular alternating arrangement of an organosilicon unit and a ?-electron system (phenylene or ethynylene)

Proton Addition to Silylstyrenes: Overcoming the Predilection for Protiodesilylation

Normally, organosilyl nucleophiles such as vinylsilanes and allylsilanes undergo protiodesilylation reactions with protons.To favour addition reactions under these conditions, the ligands on silicon have been modified such that the leaving group ability and, simultaneously, the β-effect of the silyl group is reduced.In the case of allylsilanes, the use of dichlorosilyl groups does not significantly favour addition over substitution processes at the olefin.However, with vinylsilanes bearing a second ?-nucleophile, a dichlorosilyl group can be used to regioselectively direct the formation of two bonds (C-H and C-C) sequentially in a process in which the silicon is not lost from the molecule, but may ultimately be cleaved leading to the formation of diols.Thus, benzyldichlorostyrylsilane 7, after cyclization to 9 in the presence of triflic acid, is converted into diol 12.The synthetic utility of this process is restricted by the relatively low reactivity of the styryl ?-system and the necessarily reactive electrophiles needed to initiate the process.The effect of changing from electron-donating groups to electronegative groups on silicon on reaction mechanism is discussed.

Allyldimethylsilyl triflate: a self-catalyzed silyl nucleophile

Allyldimethylsilyl triflate 2 may be prepared by a protiodesilylation reaction between diallyldimethylsilane and triflic acid.This compound possesses both a silyl-substituted carbon nucleophile and the Lewis acid necessary for activation of an electrophile.Upon exposure to an aromatic aldehyde (e.g., p-MeOC6H4CHO), the homoallylic alcohol 4 is formed in good yield.The synthetic advantages of the intramolecular Cope-type cyclization reactio are discussed.

Synthesis and reactions of silanes containing two triflate groups

1,2-Bis(trifluoromethanesulfonyloxy)tetramethyldisilane (1) and dimethylsilylbis(trifluoromethanesulfonate) (2) have been prepared via displacement of phenyl, chloro, and methyl groups in the corresponding mono- and di-silanes.Phenyl groups are displaced more rapidly than chloro and methyl groups.The unreacted groups are strongly deactivated by the presence of a triflate group at the same silicon atom.The deactivation is much weaker when a triflate group is present at the adjacent silicon atom.Alcohols and amines react more rapidly with ditriflates than with monotriflates.
