Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 224311-51-7, C20H27P.

The synthesis of poly-yne polymers containing transition metals inserted in the main chain has been attempted by reacting a dialkyne molecule, 4,4?-diethynylbiphenyl (or DEBP), with [PtCl2(dppe)] and [PdCl2(dppe)], the platinum- and palladium-cis square-planar dichlorine complexes containing diphenylphosphine ethane (dppe) as bidentate ligand. The aim of this work was to obtain organometallic polymers ([Pt(dppe)DEBP]n and [Pd(dppe)DEBP]n, respectively) having an all-cis ‘zigzag’ structure, by formation of a sigma-acetylide bond between the transition metal complexes and the dialkyne molecule. When [PtC12(dppe)] was reacted with DEBP, the formation of a chlorine-terminated [Pt(dppe)DEBP]n oligomer was evidenced; in the reaction involving the Pd(II) complex, on the other hand, [PdC12(dppe)] seems to catalyse the polymerisation of DEBP via opening of the triple bond, producing a poly-DEBP polymer containing Pd(II) atoms inserted in the main chain.
