| Abstract: | Double-bond migration of allylic alcohols and allylic alkyl ethers was catalytically effected with trans-Mo(N2)2(dpe)2(dpe = Ph2PCH2CH2PPh2). Decarbonylation occurred simultaneously in the case of allyl alcohol. Diallyl ether and allyl phenol ether gave the fragmentation products presumably through initial oxidative addition of the allylO bond. Allylamine was converted to N-propylideneallylamine and NH3. N,N-Dimethylallylamine was isomerized to N-trans-propenyldimethylamine, which was further transformed into 4-dimethylamino-1,3-hexadiene and dimethylamine on addition of oxygen. The catalytic allylation of methyl acetoacetate with allylic ethers and amines was achieved by use of trans-Mo(N2)2(dpe)2. |
