Preparation and Catalytic Application of MCM-41 Modified with a Ferrocene Carboxyphosphine and a Ruthenium Complex
Original language description
Reaction of 1´-(diphenylphosphino)ferrocenecarboxylic acid (Hdpf) with mesoporous molecular sieve MCM-41 gives immobilized carboxyphosphine (3), which was further reacted with [{Ru(.eta.6-p-cymene)Cl(?-Cl)}2] (1) to afford Ru-phosphine modified molecularsieve 4. Material 4 was tested as a catalyst in the reaction of propargyl alcohol with benzoic acid in toluene to 2-oxopropyl benzoate (7). The rate of the reaction with immobilized catalyst is slower and gives a lower yield compared with the homogeneous precatalyst [Ru(.eta.6-p-cymene)(Hdpf-kP)Cl2] (2) prepared from Hdpf and dimer 1. The main reaction also competes with another parallel, propargyl alcohol consuming process, which occurs also with MCM-41 itself in an absence of benzoic acid.

Příprava a katalytická aplikace MCM-41 modifikovaná ferrocen karboxyfosfinem a rutheniovým komplexem
Czech description
Reakcí 1?-(diphenylphosphino)ferrocenecarboxylové kyseliny (Hdpf) s mezoporézním molekulovým sítem MCM-41 vzniká carboxyphosphine (3). Carboxyphospine (3) dále reagoval s [{Ru(.eta.6-p-cymene)Cl(.mí.-Cl)}2] (1) za vzniku Ru/carboxyphosphine-modifikovanémolekulové síto 4. Jednduchá reakce mezi MCM-41 a 1 poskytla pouze Ru-modifikované molekulové síto 5. Materiály 4 a 5 byly testovány jako katalyzátory v reakci propargyl alkoholu s kyselinou benzoovou za vzniku 2-oxopropylbenzoátu (6). Reakce prováděny skatalyzátorem 3 jsou pomalejší a je dosaženo menších výtěžků esteru než s homogenním katalyzátorem [Ru(.eta.6-p-cymene)( Hdpf-kP)Cl2] (2), který byl připraven z Hdpf a dimeru (1). Struktura 2.CH2Cl2 byla potvrzena krystalickou difrakční rentgenovou analýzou.
