A surprisingly high stability , which cannot be explained in terms of the “corset effect” alone, characterizes the new tetrahedrane 1 (), which melts at 162°C and is transformed into the cyclobutadiene 2 at ca. 180°C. The SiMe 3 group is presumably crucial for the stabilization. Moreover, it allows further functionalization of the tetrahedrane.
