    摘要: The invention relates to a process for the hydroformylation of propylene with carbon monoxide and hydrogen to selectively form iso-butanal with respect to n-butanal, the process implementing a hydroformylation catalyst in combination with a phosphine, the hydroformylation catalyst comprising a palladium catalyst which comprises the element PdX 2 , where X is a halogen element selected from iodine I and bromine Br, the phosphine is of the form the phosphine is of the form P(R)(R')(R"), where R, R' and R" each comprise an alkyl group or an aryl group or an alkoxy group or an amino group.

    摘要: The invention relates to a method for manipulating, isolating, detecting or amplifying a target nucleic acid in a sample by hybridization with an oligonucleotide-oligocation conjugate, comprising allowing said nucleic acid to react with an oligonucleotide- oligocation conjugate comprising at least A1 and Bj linked together directly or via a linker, wherein. A, is an i-mer oligonucleotides, with i = 3 to 50, where Ai is an oligomer with naturally or non naturally occurring nucleobases and/or pentafuranosyl groups and/or native phosphodiester bonds, optionally comprising a marker group. Bj is a j-mer organic oligocation moiety, with j = 1 to 50, where B is - HPO3-R1-(NH-R2)n-NH-R3-O-, where R1, R2 and R3 are lower alkylene, identical or different, NH-R2 moieties being identical or different when n is >1; HPO3-R1-CH(X)-R3-O-, where Ri and R3, identical or different, are lower alkylene and X is putrescine, spermidine or spermine residue.
