Figure 6.15. Phosphorus detected 3ip i3c HMQC spectrum of 6.4. Proton decoupling was applied throughout but no carbon-13 decoupling was used during detection of the phosphorus FID. These data were acquired using a home-built third channel and a probe modified for triple-channel operation.

HMBC-based experiments). From the 2D spectrum it was possible to directly assign the platinum resonances of the different isomers and hence determine the isomer ratios. These data were collected on a triple-channel instrument equipped with a Broadband probe for which the broadbanded channel had been tuned to Pt.

As a result of the increased illumination as well as the increased gas-liquid contact area per unit volume, the triple-channel microreactor exhibited better performance compared to the batch reactor, or even compared to a typical dual-channel microreactor [138,139]. Moreover, the scaleup process using the microreactor revealed higher productivity than the batch reactor, which would be valuable for the practical applications in a broad range of gas-liquid chemical reactions.

This micro-chip reactor comprises a liquid inlet port which splits into two channels of equal passage [21]. These split channels merge with a third channel, which is connected to a second port for gas feed, in such way that the two liquid streams encompass the gas stream. This triple-stream feed section is followed by a long serpentine channel passage which ends in a third outlet port (Figure 5.11). 

These devices have gas and liquid streams which merge, i.e. are fed into each other, e.g. by special dual-feed, triple-feed or multiple-feed arrangements. Both phases are then passed in the same encasing, e.g. the same micro channel. From there, fragmentation of the gas stream occurs, forming a dispersion.

On the basis of these results we embarked on a systematic study on the synthesis of vinyl cations by intramolecular addition of transient silylium ions to C=C-triple bonds using alkynyl substituted disila alkanes 6 as precursors.(35-37) In a hydride transfer reaction with trityl cation the alkynes 6 are transformed into the reactive silylium ions 7. Under essentially nonHnucleophilic reaction conditions, i.e. in the presence of only weakly coordinating anions and using aromatic hydrocarbons as solvents, the preferred reaction channel for cations 7 is the intramolecular addition of the positively charged silicon atom to the C=C triple bond which results in the formation of vinyl cations 8-10 (Scheme 1). 

Chemical relaxation methods can be used to determine mechanisms of reactions of ions at the mineral/water interface. In this paper, a review of chemical relaxation studies of adsorption/desorption kinetics of inorganic ions at the metal oxide/aqueous interface is presented. Plausible mechanisms based on the triple layer surface complexation model are discussed. Relaxation kinetic studies of the intercalation/ deintercalation of organic and inorganic ions in layered, cage-structured, and channel-structured minerals are also reviewed. In the intercalation studies, plausible mechanisms based on ion-exchange and adsorption/desorption reactions are presented steric and chemical properties of the solute and interlayered compounds are shown to influence the reaction rates. We also discuss the elementary reaction steps which are important in the stereoselective and reactive properties of interlayered compounds. 

Note SRM is preferably performed on triple quadrupole, quadrupole ion trap, and Q-TOF hybrid instruments due to their ease of setting up the experiment and to their speed of switching between channels if monitoring of multiple reactions plays a role.
