Practical method for the preparation of nitrate esters

A new and cost-effective method was developed for the preparation of nitrate esters in 67-92% yields from the corresponding alkyl toluenesulfonates and sodium nitrate with a catalytic amount of tetrabutylammonium nitrate in benzene and water at 110-135°C in a sealed tube.

A New Method for Selective Conversion of Alcohols to Nitrates under Mild and Neutral Conditions

Treatment of alcohols with triphenylphosphine, N-bromosuccinimide (a positive halogen source), and silver nitrate affords the corresponding alkyl nitrates in excellent yields. - Keywords: Alkyl nitrates; alkoxyphosphonium salts; triphenylphosphine; N-bromosuccinimide; alcohols; Selective replacement of hydroxy groups by nitrate groups

New one-pot synthesis of alkyl nitrates from alcohols

Treatment of alcohols with Ph3P-I2-imidazole followed by 'in situ' reaction of the generated iodides with AgNO3 allows the mild conversion of alcohols into alkyl nitrates. Unlike previous procedures, this one requires no electrophilic nitrating conditions.
