title: η(3) -Allyl coordination at tin(II)-reactivity towards alkynes and benzonitrile.
abstract: We herein report the synthesis and characterization of a terphenyl-substituted Sn(II) allyl compound featuring an η(3)  coordination mode in solution and in the solid state. Two examples for the interesting reactivity of the allyl Sn(II) molecule are presented: Reactions with terminal alkynes result in the formation of tricyclic compounds by CC bond formation and the dimerization of two Sn moieties whereas the reaction with benzonitrile leads to a sixteen-membered ring system through CH activation.
