The visible-light-driven preparation of (hetero)aryl stannanes was carried out under both photocatalyst- and metal-free conditions via irradiation of arylazo sulfones in the presence of hexaalkyldistannanes. The reaction shows a high efficiency and a wide substrates scope. The resulting crude organotin derivatives can be directly employed in a Stille protocol.

Sandmeyer‐type stannylation: Stille coupling is one of the most powerful coupling reactions for CC bond formation, whereas there are only limited methods to access aryl stannane compounds. A mild stannylation process based on a Sandmeyer‐type transformation using aromatic amines as the starting materials is described. DCE: 1,2‐dichloroethane.

The synthesis and spectroscopic characteristics of 28 para-substituted aryltrimethyl-silicon, -germanium, and -tincompounds are described. The infrared spectra show characteristic bands at 1245–1165 (methyl bend), 840–765 (methyl rock), and 1105–1020 (in-plane aromatic H bend) cm−1; the frequency of the last band was found to depend on the sum of the aromatic substituent masses, the presence or absence

of the insertion of sulfurdioxide into the aryl carbon—tin bond of a species of 3- and 4-substituted phenyltrimethyl stannanes in anhydrous methanol has been conducted. The reaction is cleanly second order in this solvent (first order in each of stannane and sulfurdioxide) and the second order rate constants show an excellent correlation with σ+, indicating an electrophilic insertionreaction.
