  Preparation and Some Subsequent Transformations of Tetraethynylmethane

  摘要：

  Tetraethynylmethane (1) was synthesized in 10 steps and 33% overall yield from bis[(trimethysilyl)ethynyl] ketone. This route features (1) construction of the critical central quaternary center via the agency of a [3,3] sigmatropic shift and (2) installation of the fourth acetylene unit in a very sterically demanding environment. Alternative routes and model systems which were more informative than productive are also discussed. Finally, transition metal-mediated coupling of the rather unstable 1 (and derivatives) with unsaturated partners furnished a variety of relatively stable polylalkynylated species which could be manipulated without event.

  We report the first organically synthesized sp–sp3 hybridized porous carbon, OSPC‐1. This new carbon shows electron conductivity, high porosity, the highest uptake of lithium ions of any carbon material to‐date, and the ability to inhibit dangerous lithium dendrite formation. The new carbon exhibits exceptional potential as anode material for lithium‐ion batteries (LIBs) with high capacity, excellent
