1Three 2,5-dialkoxy-1,4-diethynylbenzene derivatives.

Figueira J1, Rodrigues J, Russo L, Rissanen K.

Acta Crystallogr C. 2008 Feb;64(Pt 2):o33-6. doi: 10.1107/S0108270107065523. Epub 2008 Jan 12.

2,5-Diethoxy-1,4-bis[(trimethylsilyl)ethynyl]benzene, C(20)H(30)O(2)Si(2), (I), constitutes one of the first structurally characterized examples of a family of compounds, viz. the 2,5-dialkoxy-1,4-bis[(trimethylsilyl)ethynyl]benzene derivatives, used in the preparation of oligo(phenyleneethynylene)s via Pd/Cu-catalysed cross-coupling. 2,5-Diethoxy-1,4-diethynylbenzene, C(14)H(14)O(2), (II), results from protodesilylation of (I).
