The one-pot hydroformylation–cyclization of allylbenzene derivatives by the catalyst system Rh(CO) 2 acac/ultranox626/CO/H 2 /CH 2 Cl 2 led chemoselectively to 5,6-dihydronaphthalene derivatives 5a–d in good yields. The addition of a catalytic amount of H 3 PO 4 enhanced in situ the cyclization process via the nucleophilic attack on the carbonyl group...
A new catalytic system formed of RhCl 3 , 3H 2 O as a catalyst and triethyl orthoformate, HC(OEt) 3 , as a solvent showed high catalytic activity in the reaction of hydroformylation of aryl, terminal and internal alkyl alkenes, and also cycloalkenes. The addition of the triphenyl phosphite, P(OPh) 3 , increased the selectivity toward the branched aldehydes with aryl...
