Mixed tetra-alkylstannanes R3SnR′ (R = Et, n-Pr, n-Bu and R′= Me, Et, n-Pr, n-Bu, n-Pent) and R2SnR′2 (R = n-Bu and R′ = Me, Et, n-Pr, n-Bu) can be easily prepared in a one-pot synthesis via coupling reaction of alkyl iodides R′I with R3SnX (X = Cl, I) and R2SnCl2 compounds in cosolvent-H2O(NH4Cl) medium mediated by zinc dust. Coupling also occurs with (Bu3Sn)2O. It has been verified that reactions are possible only with primary alkyl iodides; with secondary alkyl iodides the coupling reaction fails. When alkyl chlorides and bromides are used ditin compounds are obtained instead of the unsymmetrical tetra-alkylstannanes. This represents a route to hexaalkyldistannanes.

Unsymmetrical tetraorganotins, R2R1R2Sn (R=Me, R1=Bu, R2=Pe (Pe=pentyl) or Ph; R=Bu, R1=Pe, R2=Ph or Me; R=Pe, R1=Bu, R2=Me or Ph), BunR4-nSn (n=1-3, R=Me or Pe) and Pe2R2Sn (R=Me or Ph) have been synthesised.Various physical properties, including mass spectra, 1H and 13C NMR spectra, are reported.
