Interaction Between Propylene and H2O over Rh-Ir/C-Catalysts of Clusters Type. Communication 1

<p>The catalytic process of interaction between the propylene and H₂O over bimetallic Rh-Ir/C-catalysts of clusters type, has been studied. The possibility of the process interaction between C₃H₆ and H₂O according to and against Markovnikov rule are showed. The structure and state of Ru-Ir/C-catalysts surfaces were investigated by using electron microscopy.</p>

Esterification of Alkene with Cerium(IV) Sulfate in Carboxylic Acid

Reaction of alkenes [cyclohexene (1), cycloheptene (2), cyclooctene (3), 1-heptene (4), 1-octene (5), styrene (6), 1,7-octadiene (7), indene (8), and 1,2-dihydronaphthalene (9)] with cerium(IV) sulfate (CS) in carboxylic acids [formic acid, acetic acid, and propionic acid] readily yielded the corresponding carboxylic esters. This addition reaction follows the Markovnikov rule. This reaction provides a new simple method for preparing carboxylic esters from alkenes. It was also found that this method is useful for formylation.
