The sensitivity of organometallic catalysts to oxygen, water, and heteroatom functionalized substrates has often hampered their evolution from research laboratories to full-scale, on-line industrial processes. Polymerizations using group VIII metals are preceded by a sometimes lengthy initiation period that effectively limits their usefulness. It is during this initiation period that a small amount of reactive metal carbene is formed which then very rapidly polymerizes the cyclic olefin present. During efforts to decrease this initiation period the authors found that rigorous exclusion of water from the reaction mixture actually had an unexpected effect. Rather than deactivating these metal catalysts, water actually acts as a cocatalyst by dramatically decreasing the initiation period required for the reaction. The unusual finding eventually culminated in the discovery that the polymerization of the 7-oxanorbornene derivatives proceeds rapidly in water alone to produce the desired ROMP polymer in nearly quantitative yields.
