Aluminum phthalocyanine: an active and simple catalyst for cyanosilylation of aldehydes

Abstract

Aluminum phthalocyanine (AlPc) in the presence of Ph 3 PO acts as a highly effective catalyst for cyanosilylation of various aldehydes to the corresponding cyanohydrin trimethylsilyl ethers. The reaction proceeds smoothly with 5 mol% catalyst loading at room temperature, giving up to 96% yield.

Manganese‐Based Metal–Organic Frameworks as Heterogeneous Catalysts for the Cyanosilylation of Acetaldehyde

“…Moreover, 80 % conversion is achieved after three hours, which is comparable with literature values obtained with homogeneous Lewis acids. [27] This time, def could not be detected by GC. Next, the reaction was carried out with freshly prepared MOF 1 that was dried just before its use as catalyst.…”

Organocatalytic synthesis of cyanohydrin trimethylsilyl ethers by potassium 4‐benzylpiperidinedithiocarbamate under solvent‐free conditions

“…Accordingly, 2 mol% catalyst loading under solvent-free conditions at room temperature was found to be the optimal All products are known and were well-characterized by IR and NMR spectral data as compared with those obtained from authentic samples or reported in the literature.

Metal Phthalocyanines Catalyzed Selective Organic Transformations: Recent Developments and Promising Future

“…AlPc catalyzed cyanosilylation of aldehydes and ketones [12,13], PdPc catalyzed Suzuki and Heck coupling reactions [14] and CoPc catalyzed oxidation of alcohols and thiols [15]. MPcs have also been utilized in several photocatalytic transformations such as degradation of pollutants, oxidation of alkanes and alkenes, ene reaction etc.…”
