Yield:496-12-8 75%

Reaction Conditions:

platinum in tetrahydrofuran

Steps:

1 Isoindoline
EXAMPLE 1 Isoindoline The reaction was carried out in an autoclave. 20 g of 5% platinum on carbon are added to 100 g of phthalonitrile dissolved in tetrahydrofuran. After purging with nitrogen, the mixture is heated at 60° C. and a hydrogen pressure of 180 bars is applied for 5 to 6 hours. After decompression and purging with nitrogen, the catalyst is removed by filtration. The tetrahydrofuran is distilled off from the filtrate at atmospheric pressure, and then isoindoline is in turn distilled off from the residue under a vacuum of 23 mbars. at a temperature of 100° C. Isoindoline is thus obtained with a yield of 75% and purity of 89%.
