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 organo...

Description
Summary: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 4π+2π cycloaddition reactions with functionalized 7-oxanorbornene derivatives giving stereospecifically 7-silanorbornene products in good reaction yields.
