Tetrachloro-o-benzoquinone (1) reacts as heterodiene with 7-acetoxyquadricyclane (3) to give 4 and 5 and as electron deficient monocarbonyl compound to give 6. 1:2-adducts (8, 9) were also isolated, which presumably result from a primarily formed homodiene adduct (13) through a consecutive reaction with 3. The structures of 8 and9 have been identified by X-ray analysis.

Use of a tandem ring-opening–ring-closing metathesis (RORCM) strategy for the synthesis of functional metathesis catalysts is reported. Ring opening of 7-substituted norbornenes and subsequent ring-closing metathesis forming a thermodynamically stable 6-membered ring lead to a very efficient synthesis of new catalysts from commercially available Grubbs’ catalysts. Hydroxy functionalized Grubbs’ first- as well as third-generation catalysts have been synthesized. Mechanistic studies have been performed to elucidate the order of attack of the olefinic bonds. This strategy was also used to synthesize the ruthenium methylidene complex.

Paragraph 0301, (2013/09/26)
The present disclosure features a strain-promoted [2+2+2] reaction that can be carried out under physiological conditions. In general, the reaction involves reacting a pi-electrophile with a low lying LUMO with a quadricyclane on a biomolecule, generating
