Perchlorotriphenylene
Others have suggested that "severe molecular twisting to relieve steric
interactions of 'ortho' chlorines may preclude any stable existence [for
perchlorotriphenylene]." In fact, although it is difficult to prepare,
this highly distorted chlorocarbon is perfectly stable under ordinary
conditions. For a brief communication describing its synthesis and
X-ray structure, see
