## Abstmct: Alkylation of aaknine ( 6 ) with dialkylpropargyl chioriaks 3a and 3b gave I@-and fl-acetylenes 7a, 7b and 94.96 accompanied by @-allenes 8a, 8b. Bromoallene 104 gave only 7a and 7b but no allene &a. Reaction of propargyl chloride with 6 led on& to fl-propargyladenine ( 7c ) whereas clJo
Ethylene and styrene derivatives reacted with various propargylic ethers in the presence of zirconocene(II) to afford allenic products in high yields. The reaction proceeded via formation of
