标题 :Preparation of 2-(2'-thienyl) alkylamines and derivatives thereof and synthesis of 4,5,6,7- thieno [3,2-c] pyridine derivatives therefrom
发明人：KHATRI HIRALAL N; DEHOFF BRADLEY S
权利人:SANOFI SA
摘要:An improved process for the synthesis of 2-(2 min -thienyl)ethylamine from suitably functionalized derivatives of 2-(2 min -thienyl)ethanol employing ammonia gas in the presence of a metal salt or liquid ammonia and alkyl ketone as a solvent. The 2-(2 min -thienyl)ethylamine produced by this process is advantageously converted to the carbamic acid salt, which is suitably reconverted to 2-(2 min -thienyl)ethylamine, a useful intermediate in the synthesis of ticlopidine.

摘要:The present subject matter relates to compositions containing and synthesis of fluorescent materials e made from tetraphenylethylene (TPE) derivative compounds exhibiting aggregation induced emission (AIE) properties. Further contemplated herein are applications for TPE derivative compounds such as electroluminescent devices since they have a high efficiency, low turn on voltage, and excellent brightness. Additionally, application of TPE derivatives exhibiting AIE properties in various fields such as OLEDs, fingerprinting and forensic technology, and various other biological and industrial sectors are discussed.

摘要:A method is directed to synthesis of poly(triphenylacrylonitrite)s (PTPANs) comprising polycoupling dibromoarenes, internal diynes, and potassium ferrocyanide, resulting in polycoupled dibromoarenes, internal diynes, and potassium ferrocyanide; and producing poly(triphenylacrylonitrite)s (PTPANs) by catalysis of the polycoupled dibromoarenes, internal diynes, and potassium ferrocyanide with palladium acetate and sodium bicarbonate, wherein the catalysis is allowed to proceed in dimethylacetamide under nitrogen at a prescribed temperature for a prescribed time. Further, poly(triphenylacrylonitrite)s (PTPANs) is a polymer and comprises a backbone structure of n nwherein x and y are integers;n nwherein each R is independently selected from the group consisting ofn n nandn nwherein each R′ is independently selected from the group consisting of
