1. | By polymerizing various monomers in the presence of transition-metal salts (e.g., WCl6) and a Grignard reagent, disproportionation catalysts containing a carbochain polymeric support have been obtained. Lewis acids were used as cocatalysts for the disproportionation of the olefins. |
2. | The activity and selectivity in the action of the catalytic systems obtained have been studied as a function of the nature of the cocatalyst, the ratio of the components, and the nature of the solvent in the disproportionation of 2-pentene. |

Optically active (\t-)-(1R,2R,3R) aminoesters of isopinocampheol (2,6,6-trimethylbicyclo[3.1.1]heptan-3-ol) were synthesized from (+)-α-pinene. The antifidant,
juvenoidal, growth-regulating, and herbicidal activities of the newly synthesized compounds were studied.

The conditions for the acylation of (?)-menthol with monochloroacetyl chloride have been studied. Amino esters of (?)-menthol have been obtained by the nucleophilic replacement of the chlorine in (?)-menthol monochloroacetate by residues of secondary amines. Their properties and their mass, IR, and13C NMR spectra are described. 相似文献
