Diazo-functionalized monomers

Copolymerization with diazo-functionalized monomers in emulsion has been employed for the preparation of highly cross-linked poly(methylmethacrylate) lattices with diazo groups covalently fixed to the core (Figure 22). Thermal decomposition of the diazo groups allowed selective grafting of a shell [254-256]. 

Moreover, each of the four ortho carbons is also protected from the approach of external reagents by these bromine groups. This stabilization enabled us to introduce connecting groups at the para position of the monomer diazo compound (e.g., 119) to give the functionalized monomer 120, and then to connect it to an appropriate linker satisfying the topological requirement for intramolecular... 

Functionalized diazo dye monomers, (II), were prepared by Hagting et aL (3) and used to prepare ophthalmic lenses that absorbed light between 400 and 550 nm. 

Following the setup first described by Sinner et Arstad et al ° homopolymerized phosphane-containing monomers with the second-generation Grabbs initiator, cross-linked with p-di(norbom-2-ene-5-yl)benzene and used in the halogenation of alcohols. In a similar approach, an ethyl- l-diazo-2-oxopropylphosphonate-functionalized resin was prepared and used for the conversion of aldehydes into 1-alkynes. Fuchter et also developed a ROMP cap-...
