Rearrangement of Epoxides Using Modified Zeolites

Effect of aluminium incorporation by the “pH-adjusting” method on the structural, acidic and catalytic properties of mesoporous SBA-15

“…As previously reported, this reaction can be easily accomplished in the presence of Brönsted and Lewis acids [67] or bases [68]. Porous materials, such as zeolites, with moderate-strong acid sites [69][70][71] and amorphous silica-alumina having weak-moderate acid sites [72,73] have been used as effective acid catalysts for styrene oxide isomerization in liquid and gas phase.…”

Regioselective Electrophilic Aromatic Substitution Reactions over Reusable Zeolites

“…These systems include Brφnsted or Lewis acids [177][178][179][180] give a good yield of phenylacetaldehyde [190][191][192][193]. Also, rearrangements of different epoxides over acidic zeolites at 200-300 °C have been reported [194].…”

Regioselective Electrophilic Aromatic Substitution Reactions over Reusable Zeolites

“…These systems include Brφnsted or Lewis acids [177][178][179][180] [185,186], Pd(OAc) 2 in the presence of phosphine ligands [187], InCl 3 [188] and give a good yield of phenylacetaldehyde [190][191][192][193]. Also, rearrangements of different epoxides over acidic zeolites at 200-300 °C have been reported [194].…”
