Ruthenium-catalyzed diazoacetate/cyclooctene metathesis copolymerization

Abstract

As a powerful synthetic tool, ruthenium-catalyzed ring-opening metathesis polymerization (ROMP) has been widely utilized to prepare diverse polymers. In this contribution, we demonstrated the polymerization of cyclooctene in the presence...

Covalently Crosslinked Networks from Telechelic Polycyclooctene with Reinforced Properties

“…[ 10‐15 ] For example, telechelic polymers can be synthesized via direct metathesis of cyclic olefins in the presence of a bifunctional alkene chain transfer agents (CTAs) bearing different polar groups. [ 16‐24 ]…”

Synthesis and electrochromic properties of polyamines containing a 4,4′-diaminotriphenylamine-N,N′-diyl unit in the polymer backbone: Ru-catalyzed N–H insertion polycondensation of 1,4-phenylenebis(diazoacetate) with 4,4′-diaminotriphenylamine derivatives

“…[7][8][9][10][11][12][13][14][15][16][17] Along with the above-mentioned C1 polymerization, the use of bis(diazocarbonyl) compounds as a monomer for polycondensation has also been explored and demonstrated to be effective for preparing polymers with a variety of unprecedented main chain structures. [18][19][20][21][22][23][24][25][26][27][28][29][30][31] One of the examples of the polycondensation of bis(diazocarbonyl) compounds utilizes insertion of diazo-bearing carbon atoms into N-H bonds of diamine monomers, affording a variety of polyamines with unique polymer backbone structures. Indeed, the polymerization proceeded efficiently between diethyl 1,4-phenylenebis (diazoacetate) 1 and a variety of aromatic diamines, yielding polyamines bearing an alkoxycarbonyl group at the adjacent carbon of each nitrogen in the main chain framework as shown in Scheme 1.…”
