标 题 :Efficient synthesis of alkyl carbonates
发明人：JUNG KYUNG WOON
权利人:UNIV SOUTH FLORIDA
摘要:Efficient synthetic methods towards mixed aliphatic carbonates through the three component couplings of aliphatic alcohols, alkyl halides and carbon dioxide in the presence of cesium carbonate and tetrabutylammonium iode (TBAI). Due to their enhanced nucleophilicities, cesium alkoxides are smoothly incorporated into CO 2 , allowing for mild reaction conditions such as ambient temperatures and short reaction durations. Various primary and secondary substrates are compatible under the standard conditions, offering high yields, while chiral templates such as α-hydroxy carbonyls are resistant to racemization.

标题:Synthesis of Solvent Yellow 33 (D & C Yellow 11) with excess phthalic anhydride acid as a solvent
发明人：SUJEETH PUTHALATH K
权利人:WARNER JENKINSON COMPANY
摘要:A process for the manufacture of a quinophthalone, in particular Solvent Yellow 33 (D & C Yellow 11) is described. The quinophthalone, in particular Solvent Yellow 33, is made by a process in which quinaldine is condensed with a molar excess of either phthalic acid or phthalic anhydride, the acid or anhydride being employed not only as a reactant, but also as a solvent for the reaction. This process can also employ phthalic acid (or recycled phthalic acid) and phthalic anhydride together, one as the solvent and the other as the reactant.
