Strukturelle Effekte in Systemen M n Li/Butadien/Styrol

The structure of the butadiene unit C 4 H 6 in the hydrolysis products of the oligomers RM n C 4 H 6 M m 'Li and RM n C 4 H 6 Li (where R is sec ‐butyl, M and M' are perdeuterobutadiene or styrene) was estimated by the use of IR‐ and NMR‐spectroscopy. The dependency of the C 4 H 6 ‐structu...

Description
Summary:The structure of the butadiene unit C 4 H 6 in the hydrolysis products of the oligomers RM n C 4 H 6 M m 'Li and RM n C 4 H 6 Li (where R is sec ‐butyl, M and M' are perdeuterobutadiene or styrene) was estimated by the use of IR‐ and NMR‐spectroscopy. The dependency of the C 4 H 6 ‐structure on the nature of both the preceding unit M and the attacking monomer M' was investigated. The variation of the concentration of the organolithium compounds during the oligomer synthesis on the one hand, and during their hydrolysis on the other hand, showed a dependency of the C 4 H 6 ‐structure on the conditions of the respective experiments.
