Abstract
1420904 Hydantoin derivatives BAYER AG 10 April 1974 [11 April 1973] 16005/74 Heading C2C [Also in Division C3] Compounds containing at least one hydantoin or thiohydantoin group are obtained by (1) reacting mono-, di- or poly-primary amines with compounds containing at least one α-halocarboxylic acid ester group and (2) reacting the crude reaction product thus obtained with mono-, di- or poly-isocyanates or isothiocyanates. The isocyanates may be used partly or completely in the form of masked isocyanates which are obtained by reacting the free isocyanates with compounds containing reactive hydrogen. The reaction may be carried out in a solvent, e.g. an optionally substituted aliphatic or aromatic hydrocarbon solvent or a phenolic solvent.
