The Reaction Takes Place Rapidly In Nmp With Triethylsilane As A Silicon Source And Sodium Acetate To Provide Functionalized Aryltriethylsilanes In Moderate To Good Yields. Heteroaromatic Halides Also Were Found To Be Readily Silylated With Triethylsilane. The Procedure Is Chemoselective And Tolerates A Wide Variety Of Functional Groups. Doi:10.1021/ol052996U
专利号:US-9867899-B2 优先权日:2010-05-24 标题 :Reinforced adhesive complex coacervates and methods of making and using thereof 发明人:STEWART RUSSELL J 权利人:UNIV UTAH RES FOUND 摘要:Described herein is the synthesis of reinforced adhesive complex coacervates and their use thereof. The reinforced adhesive complex coacervates are composed of (a) at least one polycation, (b) at least one polyanion, and (c) a reinforcing component. The adhesive complex coacervates described herein can be subsequently cured to produce strong, cohesive adhesives. The reinforced adhesive complex coacervates have several desirable features when compared to conventional adhesives. The reinforced adhesive complex coacervates are effective in wet or underwater applications. The reinforced adhesive complex coacervates described herein, being phase separated from water, can be applied underwater without dissolving or dispersing into the water. The reinforced adhesive complex coacervates have numerous biological applications as bioadhesives and bioactive delivery devices. In particular, the reinforced adhesive complex coacervates described herein are particularly useful in underwater applications and situations where water is present such as, for example, wet tissues in physiological conditions.
专利号:US-2014220082-A1 优先权日:2011-06-28 标 题:Adhesive complex coacervates and methods of making and using thereof 发明人:STEWART RUSSELL J 权利人:STEWART RUSSELL J; UNIV UTAH RES FOUND 摘要:Described herein is the synthesis of adhesive complex coacervates and their use thereof. The adhesive complex coacervates are produced by reacting (a) at least one poly anion comprising a plurality of activated ester groups, and (b) at least one polycation comprising a plurality of nucleophilic groups, wherein the nucleophilic groups react with the activated ester groups to produce a new oovalent bond between the polycation and the polyanion. The adhesive complex coacervates described herein have low interfacial tension with water and wettable substrates. When applied to a wet substrate they spread over the interface rather than beading up. The adhesive complex coacervates have numerous biological applications as bioadhesives and drug delivery devices. In particular, the adhesive complex coacervates described herein are particularly useful in wet or underwater applications and situations where water is present such as, for example, physiological conditions.
专利号:US-9999700-B1 优先权日:2010-11-12 标 题 :Simple coacervates and methods of use thereof 发明人:STEWART RUSSELL J 权利人:UNIV UTAH RES FOUND 摘要:Described herein is the synthesis of adhesive from simple adhesive coacervates and their uses thereof. The adhesives are composed of (a) a polyanion in the absence of a polycation, wherein the polyanion comprises at least one crosslinking group capable of covalently crosslinking with itself, and (b) a sufficient amount of a complimentary multivalent cation or multivalent anion to produce the simple coacervate. The adhesives have numerous medical and non-medical applications.
