Aqueous phase homogeneous catalysis using core–shell nanoreactors: Application to rhodium-catalyzed hydroformylation of 1-octene
High catalytic activity (turnover frequencies up to 700 h) was achieved using new triphenylphosphinefunctionalized core cross-linked micelles, TPP@CCM, as nanoreactors and [Rh(acac)(CO)2] as catalyst precursor for the aqueous biphasic hydroformylation of 1-octene. While the hydrophobic core of the polymer offers an adequate environment for the catalytic reaction, its hydrophilic shell confines ...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولDiastereoisomeric bisphosphite ligands in the hydroformylation of octenes: rhodium catalysis and HP-NMR investigations.
Diastereoisomeric hydroformylation catalysts show differences for the catalyst preformation pathway and a strongly reduced n-octene hydroformylation activity for the (S,S,R)-isomer.
متن کاملCHEMOSELECTIVITY AND REGIOSELECTIVITY IN HYDROFORMYLATION The control of chemoselectivity is a fundamental concern in Rh-catalyzed hydroformylation
1 RHODIUM-CATALYZED STEREOSELECTIVE HYDROFORMYLATION Reported by Daniel Robbins October 16, 2008 INTRODUCTION Hydroformylation, the conversion of olefins into aldehydes through the addition of CO and H2, is an important industrial reaction that employs homogeneous catalysis by transition metals (Figure 1). Hydroformylation is a valuable reaction in organic chemistry because it produces aldehyde...
متن کاملGas-Phase Hydroformylation of Propene over Silica-Supported PPh3-Modified Rhodium Catalysts
Heterogeneous rhodium catalysts supported on SiO2 were modified with PPh3 for the gas-phase hydroformylation of propene to produce nand isobutanal. High selectivity to aldehydes was achieved, with no propane or alcohols formed. Investigation of the effects of reaction temperature, reactant partial pressures, total pressure, and PPh3/Rh ratio suggested that the supported catalyst behaved similar...
