Formation of a stannylstannylene via intramolecular carbene addition of a transient stannaacetylene (RSn[triple bond, length as m-dash]CR').
Photolysis of diazomethylstannylene [, Me(3)SiC([double bond, length as m-dash]N(2))(Ar)Sn:, Ar = C(6)H(3)-2,6-Tip(2), Tip = C(6)H(2)-2,4,6-(i-Pr)(3)] afforded unusual stannylstannylene via intramolecular carbene addition to an aromatic pi bond of stannaacetylene ; the structures of compounds and were fully characterized by X-ray crystallography.
