Trimethylsilyl Cyanide Addition to Carbonyl Compounds Under Neutral Condition Catalyzed by Iodine

Reaction of trimethylsilyl cyanide with aliphatic or aromatic aldehydes and ketones in the presence of a catalytic amount of elemental iodine produced the corresponding cyanohydrin trimethylsilyl ethers in very short time and high yields.     

A Review of: “Natural and Synthetic Polymers by Henry L Bolker Marcel Dekker,Inc., New York, 1974”

Grafting to fibers has been studied extensively since the early 1950s as a technique for modifying their properties. Extensive reviews are available on this general subject [l-41. Although the main emphasis has been with textile fibers, considerable work has also been carried out with paper-making fibers and on paper itself [l,5].     

An Improved Method for the Synthesis of N-Phenoxyacetylribonucleosides

N-phenoxyacetylribonucleosides were prepared efficiently from the reaction of ribonucleosides with phenoxyacetylchloride and 1,2,4-triazole(for adenosine and cytidine) or 1-hydroxybenzotriazole (for guanosine).
