Hydrogen in situ

Derivatives of CPD have also been incorporated into these resins. CPD and 2-butene-l,4-diol have been condensed in ethanol and catalyticaHy hydrogenated in situ to give 2,3-bis(hydroxymethyl)bicyclo[2.2.1]heptane (51). This latter compound is used as a chain extender in polyesters for engineering plastics (52). 

Hydrogenation of benzo-TA 254 by hydrogen in situ in Sn/HCl leads to the ring cleavage and the formation of 2-mercaptobenzoic acid and arylamides (60MI1) (Scheme 99). 

N-substituted 2-aminomethylpyrrolidines can be prepared by the reduction of the corresponding N-substituted 2-nitromethylenepyrrolidines with hydrogen "in situ" [2 ], or by the catalytic hydrogenation [2, 3, 4] according to the scheme ... 

A recent approach to the study of fuel cell oxidations has used mass spectroscopy directly coupled to the cell [29], since the mass spectrum allows a clear definition of whether an observed current is due to the formation of CO2 or merely the oxidation of hydrogen. In situ IR spectroscopy is another promising method these experiments clearly show that adsorbed carbon monoxide is formed during the pulsed oxidation of all small molecules containing carbon. Unfortunately, the time taken to record a spectrum, typically 10 minutes, and the pulse modulation essential to obtain the sensitivity, make uncertain the interpretation of these observations in the context of data obtained on clean surfaces after only a few milliseconds.
