Procedure

The above data confirm that after the initial selective or preferential hydroformylation of the 1-alkene (propene) fraction to n-butyraldehyde is essentially complete (>95% conversion after about 6 hours), the remaining 2-hexene fraction may be hydroformylated to iso-heptaldehydes using the same catalyst solution and the same reaction conditions. In this way, the complex PtCl2 [P(C6H5)3 ]2 -SnCl2 allows sequential hydroformylation of the α-olefin-internal olefin mixture of propene and 2-hexene.
