    Abstract: Preparation of highly reactive isobutene homo- or copolymers having M n =from 500 to 45 000 by polymerizing isobutene in the liquid phase in the presence of a dissolved, dispersed or supported boron-containing catalyst complex, by using, as the catalyst complex, a protic acid compound I [H + ] m+1 [R 1 R 2 R 3 B-(-A m+ -BR 5 R 6 -) n -R 4 ] (m+1)- .L x (I) R 1 to R 6 each independently aliphatic, heterocyclic or aromatic, fluorinated hydrocarbon radicals having in each case from 1 to 18 carbon atoms, or silyl groups comprising C 1 to C 18 hydrocarbon radicals, A nitrogen-containing bridging member which forms covalent bonds to the boron atoms via its nitrogen atoms, L neutral solvent molecules, n=0 or 1, m=0 or 1 and x is >=0.

    Abstract: Processes for preparing a C5 aldehyde and propene are disclosed, the processes comprising: (a) providing a feedstream, the feedstream comprising butane, 1-butene, 2-butene and 1,3-butadiene, the 1,3-butadiene present in the feedstream in an amount up to 1000 ppm; (b) contacting the feedstream with hydrogen and carbon monoxide in the presence of a hydroformylation catalyst to form a 2-butene-rich butane stream and a C5 aldehyde; (c) separating the 2-butene-rich butane stream and the C5 aldehyde; and (d) contacting the 2-butene-rich butane stream with ethene in the presence of a metathesis catalyst to form a propene-containing hydrocarbon stream.
