Sintese en reaksies van dialkeen- en -alkynderivate van pentasiklo[5.4.0.02,6.03,10.05,9]undekaan-8,11-dioon.

The reaction of 3 with alkene- and alkyne alcohol derivates in the presence of p-toluene sulphonic acid and benzene yielded the dienes (5,6) and diynes (4,7). The reaction of 4 with the Mo(CO)6/ phenol catalyst system gave polymeric products, while the reaction of 5 with Grubbs 1 led to ring-closing metathesis (RCM). [ABSTRACT FROM AUTHOR]
