Titanocene dichloride–Lewis base: An efficient catalytic system for coupling of epoxides and carbon dioxide

Quaternary onium modified SalenCoXY catalysts for alternating copolymerization of CO2 and propylene oxide: A kinetic study

“…According to our previous reports [34][35][36][37][38][39][40], the counter anion of the quaternary onium strongly influenced the coupling reaction of epoxide with carbon dioxide and a more facile leaving group of nucleophile exhibited a better activity in the synthesis of cyclic carbonate. Therefore, SalenCo complexes 4Ea, 4Eb and 4Ec were devised and prepared by using the anion of Cl À , Br À and NO 3 À respectively.…”

Titanium Alkoxide Complexes as Catalysts for the Synthesis of Cyclic Carbonates from Carbon Dioxide and Epoxides

“…However, there are only three reports on titanium complexes in catalytic synthesis of cyclic carbonates: [Cp 2 TiCl 2 ] with a Lewis base [17] or KI [18] and a series of titanium complexes [ onate under benign conditions (100°C, 15 bar CO 2 , 3 h) with turnover frequencies of up to 116 h -1 . The effect of reaction parameters such as pressure, temperature, and catalyst/cocatalyst molar ratio were also studied in order to optimize the catalytic system.…”

A novel supported salenCrIIICl catalyst for alternating copolymerization of cyclohexene oxide with carbon dioxide

“…The development of efficient catalytic processes for CO 2 transformation into economically, environment friendly products is of great interest and a long-standing goal for chemists all over the word [3][4][5][6][7][8]. The eminent process is the use of CO 2 as a C1-feedstock in the production biodegradable polycarbonates by alternating copolymerization of CO 2 and CHO, which was first reported by Inoue et al in 1969 with a very low react rate and activity [9].…”
