The acceptance of new chemical ideas, before the Chemical Revolution of Lavoisier, in Greek-speaking communities in the 17th and 18th centuries did not create a discourse of chemical philosophy, as it did in Europe, but rather a “philosophy” of c

The ring-opening polymerization of bicyclo[2.2.1]-hept-2-ene (norbornene, NBE) is carried out with the metathesis catalysts WCl6/RLi, where R=Me-, n-Bu-, sec-Bu-, tert-Bu-, sec-Bux-C60x−, sec-Bu-CH2C(Ph)2−, PS−. The bulkiness of the R chain

We study the polymerisation of a series of unstrained cyclic and acyclic dienes with the catalytic system of Mo(CO)5PPh3/alkylaluminum. The Mo(CO)5PPh3/alkylaluminum catalyse the nonmetathesis polymerisation, through a pair of ionic complexes similar
