High pressure synthesis of novel organometallic electron donor - electron acceptor polycyclic dyads

Preparation of novel electron-transfer dyads (donor-acceptor molecules) with novel molecular architecture and well-defined donor/acceptor geometrical orientation is presented. High pressure (HP) promoted synthesis of electron donor-acceptor dyads possessing rigid polynorbornene frameworks and organometallic (7-silanorbornadiene) moiety is discussed in detail. Under HP conditions, cyclic organometallic diene, 1-sila-2, 3, 4, 5-tetraphenyl-1, 1-dimethyl-cyclopenta-2, 4-diene undergoes facile [4p+2p] cycloaddition reactions with functionalized 7-oxanorbornene derivatives giving stereospecifically 7-silanorbornene products in good reaction yields.
