Beschreibungen/Notizen

• The electrophilic N‐alkynylation of cyano ligands by alkynyliodonium salts provides a convenient route to metal‐coordinated forms (1a–c) of the “interstellar” ethynyl isocyanide 2a (which can only be isolated in trace amounts in the laboratory) and other new members (2b, 2c) of this class of compounds. Alkynyliodonium compounds with Ralkyl react differently: instead of undergoing a 1,2‐alkyl migration, the isocyanovinylidene intermediate is stabilized by insertion into the (alkyl)CH bond.
