Conclusions
-
1.
The telomerization of propadiene by morpholine in the presence of palladium chloride and triphenylphosphine leads mainly to the formation of conjugated alkadienylmorpholine CH3C(CH2)C(CH2)CH2NC4H8O. Allylmorpholine, nonaminated propadiene oligomers, and high-molecular-weight products are formed together with (2,3-dimethylenebutyl)morpholine, with the composition of the products depending on the ratio of propadiene to morpholine.
-
2.
Allylmorpholine is not an intermediate reaction product, and the formation of it and (2,3-dimethylenebutyl)morpholine occurs as a result of parallel reactions.
