Conclusions
-
1.
When tetra-n-propyldiborane acts on n-butyl vinyl ether, di-n-propyl-(2-n-butoxyethyl)boron is formed, which is converted at room temperature with evolution of ethylene to the n-butyl ester of di-n-propylboric acid.
-
2.
Tetra-n-propyldiborane adds to esters of allyl- and allylthioboric acid with the formation of unstable din-propyl-(2-methoxyborylpropyl) boron or di-n-propyl-(2-methylmercaptopropyl)boron, which decompose to esters of di-n-propylboric or di-n-propylthioboric acids and polymers (-CH2- CH2-CH2B-X)n.
