Efficient catalysts for telomerization of butadiene with amines
摘要:
In situ-generated N-heterocyclic carbene (NHC) palladium catalysts and isolated NHC-palladium complexes have been tested for the telomerization reaction of 1,3-butadiene with primary and secondary amines. Superior catalyst activity (TON up to 400.000) and selectivity are obtained. Applying optimized conditions a variety of octa-2,7-dienylamines were prepared in high yield and excellent selectivity.

The present invention relates to a (meth)acrylate monomer of the general formula (I)
in which R
1
is hydrogen or a methyl group, X is oxygen or a group of the formula NR′ in which R′ is hydrogen or a radical having 1 to 6 carbon atoms, R
2
is an alkylene group having 1 to 22 carbon atoms, Y is oxygen, sulphur or a group of the formula NR″, in which R″ represents hydrogen or a radical having 1 to 6 carbon atoms, and R
3
is an unsaturated radical having 8 carbon atoms and at least two double bonds.
The present invention further relates to a process for preparing the monomers set out above, to polymers obtainable from this monomer mixture, and to coating materials which comprise the stated polymers.
