Alkoxide initiation of anionic polymerization of masked disilenes to polysilanes

The polymerization of masked disilenes initiated by potassium alkoxides in the presence of cryptand[2.2.2] in benzene proceeded in a living manner, especially when using potassium (−)-menthoxide. The molecular weights of the polysilanes thus obtained were in good agreement with the calculated values...

Summary:The polymerization of masked disilenes initiated by potassium alkoxides in the presence of cryptand[2.2.2] in benzene proceeded in a living manner, especially when using potassium (−)-menthoxide. The molecular weights of the polysilanes thus obtained were in good agreement with the calculated values.
