Bicyclo[10.10.10]dotriacontanes: the Largest Bicyclo[n.n.n]alkane Ever Known

Bicyclo[10.10.10]dotriacontanes, the largest bicyclo[n.n.n]alkanes ever known, have been first synthesized by Raney nickel reduction of trithienylmethanophanes consisiting of two tris(2-thienyl)methanes and three etheno bridges. X-ray crystallographic analysis of a crystalline derivative confirmed the structure, though disorder of included hexane molecules lowered the accuracy.
