| Abstract: | The structure of the butadiene unit C4H6 in the hydrolysis products of the oligomers RMnC4H6Mm'Li and RMnC4H6Li (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 C4H6-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 C4H6-structure on the conditions of the respective experiments. |
