Insertion reactions of CO2, OCS, and CS2 into the Sn-N bonds of (Me2N)2Sn: NMR and X-ray structural characterization of the products

► Syntheses of Sn(II) carbamates, thiocarbamates, and dithiocarbamates. ► Direct insertion reactions of the heteroallenes CO2, OCS, and CS2. ► Products contain bridging or chelating ligands as shown by X-ray crystallography. ► Discussion of solid-state geometries and reasons for the various structural motifs.
