✦ Synopsis

Conjuring with conjugation: catalysis by ruthenium-allenylidene complexes has been observed for the conversion of tin hydrides into distannanes and dihydrogen. Alkyne or alkene groups (R) in conjugation with an aromatic ring are required for catalytic activity, providing an unusual example of control of metal-centered reactivity by a remote substituent.

Dehydrogenative coupling of tertiary stannanes, R 3 SnH, catalyzed by a transition metal is known to produce distannanes, R 3 SnÀSnR 3 , [1] whereas a mixture of cyclic and linear oligo-or polystannanes is obtained from the analogous dehydrogenative coupling of secondary stannanes, R 2 SnH 2 . [2][3
