标题 :Synthesis of fluorinated xanthene derivatives
发明人:KLAUBERT DIETER H; GEE KYLE R
权利人:MOLECULAR PROBES INC
摘要:Facile syntheses for fluorinated resorcinol and aminophenol derivatives are provided that yield isomer-free products in good yield. These novel methods use generally available precursors and standard laboratory reagents and equipment to reproducibly produce these synthetically useful reagents in relatively large quantities. The resulting fluorinated resorcinols and aniinophenols possess utility in the preparation of fluorinated fluorescein and rhodol dyes.

标 题 :Solvent systems for synthesis of poly(amic acid) and polyimide polymers
发明人:KIM EUNGKYU; HARRIS WILLIAM J; JIANG QI; JIANG XIN; OHBA KAORU
权利人:DOW GLOBAL TECHNOLOGIES LLC
摘要:The process for synthesizing a poly(amic acid) polymer or a polyimide polymer is improved by using a solvent system consisting essentially of: (A) a first component consisting essentially of at least one of a sulfoxide, e.g., DMSO, and an alkyl phosphate, e.g., triethyl phosphate, and (B) optionally, a second component consisting essentially of at least one aprotic glycol ether, e.g., dipropylene glycol dimethyl ether.
