摘要:
Diene Oligomerization. XV. Palladiumcomplexcatalyzed Telomerization of Butadiene with Amines and Dimerization in the Presence of KetoximesButadiene reacts with primary or secondary amines and with the homogeneous catalytic system bis‐acetylacetonatopalladium‐(II)/triphenylphosphine to form 1‐amino‐octa‐2,7‐dienes. The rate and the selectivity of the reaction increase in presence of cocatalysts as triarylphosphates instead of triphenylphosphine and if the reaction proceeds in a protic media — in alcohols, water or lower carboxylic acids. A number of 1‐aminoocta‐2,7‐dienes were prepared. If oximes act as organic nitrogen compounds, only n‐octa‐1,3,7‐triene is selectively formed. Schiff' bases aldolisate under the c
