ReactIR system

PCA techniques have been applied to various data sets. From the open literature, I have been unable to find reference to their application to homogeneous catalytic systems. Having said that, it is important to note that the new ReactIR system by Mettler Toledo contains a program ConcIRT. It is a proprie-... 

Spectral investigations of the catalytic resting states in both asymmetric hydroformylation and hydrocyanation using bisphosphite 1 were performed. Reaction of Rh(CO)2(acac) with 1 equiv of i under 1 1 CO/H2 led to clean formation of Rh(l)(CO)2H. Infrared spectra of the reaction product exhibited bands at 2069, 2015 and 1984 cm. Extensive characterization of this complex by NMR has been published by van Leeuwen.(4) Under 50 psi l.T CO/H2 in the presence of styrene, identical bands were observed by in situ IR using the ReactIR system. 

ReactIR refers to the real time, in situ monitoring of the IR spectrum of the reaction mixture with a ReactIR 4000 Reaction Analysis System available from AS I Applied Systems.

We have conducted a series of kinetic investigations on controlled cationic isobutylene (IB) polymerizations at high temperature, i.e., -10°C, utilizing in situ ATR-FTIR spectroscopy (ReactIR 1000, ASI Applied Systems, Inc.). Our goal was to produce nearly monodisperse...
