WebMay 31, 2004 · Initial formation of the vinylic radical 15 and subsequent hydrogen abstraction from a transannular activated methylene group (1,5-or 1,6-HAT, respectively) yields the secondary alkyl radicals 16a and 16b. These species may now cyclize to the remaining C=C double bond in a 5-exo or 6-exo fashion, respectively . WebA simple and an efficient approach has been developed for the synthesis of polyesters containing pendant thiolactone units. For this purpose, polyester P1 possessing electron deficient triple bonds in the main backbone was prepared, and subsequently reacted with benzyl-azide and thiolactone-azide (TLa-N 3) at a mole ratio of 2:1 (per alkyne), through … WebCatalyst-Free Multicomponent Tandem Polymerizations of Alkyne and Amines toward Nontraditional Intrinsic Luminescent Poly(aminomaleimide)s. ...

Alternatively, 1-alkynes can be used. In this case, the term 1-alkyne polymerization applies. This reaction proceeds via a- or j6-insertion of the alkyne into the metal-carbon double bond (Scheme 1).
