Yield:401-80-9 44%
Reaction Conditions:
with tert.-butylnitrite;boron trifluoride diethyl etherate in 1,2-dichloro-benzene at 90; for 0.666667 h;Balz-Schiemann Reaction;
Steps:
2
Examples 2 to 6; Before describing the examples in detail, the procedure which is used in all the examples is specified. An aminoaromatic compound in a solvent (o-dichlorobenzene or benzonitrile) is slowly introduced onto a BF3.Et2O heel (1.4-1.5 molar equivalents) at a temperature of less than 0° C. or onto a BF3.2H2O heel (1.4-1.5 molar equivalents) at ambient temperature in a three-necked round-bottomed flask equipped with a reflux condenser, a thermocouple and a stirring system. t-Butyl nitrite in the same solvent is then added at ambient temperature and then the reaction medium is heated at the temperature specified in the table below and according to the time shown. The results are recorded in table (I). Table I
