(4+2)-cycloaddition of nitroalkenes with ynamines; formation of a 4H-1,2-oxazine 2-oxide derivative [PDF]
, 1980 The formation of a thermally unstable (4+2)-cycloadduct, a 4H-1,2-oxazine 2-oxide derivative ( ), from the reaction of 1-nitrocyclopentene with 1-phenyl-2-(1-pyrrolidinyl)acetylene has been proven by the structure elucidation of isoxazole derivative ...

Homoleptic Bismuth Alkynes: Isolable Reagents for Selective Alkynyl Radical Transfer
Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.The first series of fully characterized homoleptic alkynyl bismuth compounds Bi(C≡CR)3 is presented. Facile homolytic Bi–C bond cleavage grants access to alkynyl radicals, which have been employed in selective C–X bond formation (X = C, B, Se, Te). This complements existing strategies for alkynyl radical generation as it proceeds under mild and purely ...
