Patent number: 8168833Abstract: Embodiments of the invention provide a method of using Schwartz Reagent, Cp2Zr(H)Cl, without accumulating or isolating it. Methods provide mixtures of Cp2ZrCl2, reductants that selectively reduce Cp2ZrCl2, and substrates.

Substrates include tertiary amides, tertiary benzamides, aryl O-carbamates, and heteroaryl N-carbamates, which are reduced to aldehydes, benzaldehydes, aromatic alcohols, and heteroaromatics, respectively. Compared to prior methods, reagents are inexpensive and stable, reaction times are short, and reaction temperature in certain cases is conveniently room temperature. It has been estimated that using the in situ method described herein instead of synthesized or commercially obtained Schwartz Reagent provides a 50% reduction in cost.Type: GrantFiled: December 3, 2009Date of Patent: May 1, 2012Assignee: Queen's University at KingstonInventors: Yigang Zhao, Victor A.

(each R1 independently represents a group selected from an alkyl group having 1 to 30 carbon atoms, a fluorine-substituted alkyl group having 1 to 30 carbon atoms, an aryl group having 6 to 30 carbon atoms, and an aralkyl group having 6 to 30 carbon atoms; Y represents a polyvalent alcohol compound residue; M represents any of a hydrogen atom, an alkaline metal atom, an ammonium ion, and an alkylammonium ion; and reference character m represents an integer of 0 to 300.) There can be an organopolysiloxane capable of providing a cosmetic having excellent emulsion stability, excellent powder-dispersion stability if powders are contained therein, and excellent skin affinity and cosmetic durability, due to a novel organopolysiloxane having a specific structure containing a nonionic hydrophilic group and an anionic hydrophilic group of a carboxylic acid structure; and a cosmetic containing it.Type: ApplicationFiled: July 13, 2011Publication date: February 16, 2012Applicant: SHIN-ETSU CHEMICAL CO., LTD.Inventor: Masanao KAMEI

Patent number: 8110613Abstract: Provided is a method for efficiently producing a cationically curable condensed silicon compound. There was an unsolved problem that, in a condensation reaction, an oxetanyl group is subjected to ring-opening under an acidic condition, while gelation is easily caused under an alkaline condition. It was found that a silicon compound (C) having an oxetanyl group can be obtained without causing gelation even at a high concentration by the present method including a first step of separately subjecting a silicon compound (A) having four siloxane bond-forming groups and a silicon compound (B) having an oxetanyl group to alcohol exchange reaction with 1-propanol and a second step of subjecting silicon compounds (AP) and (BP) undergone the first step to hydrolytic copolycondensation under an alkaline condition at a specific ratio.Type: GrantFiled: December 14, 2009Date of Patent: February 7, 2012Assignee: Toagosei Co., Ltd.Inventors: Sayaka Oike, Akinori Kitamura, Hiroshi Suzuki
