Symmetrical dibenzylureas are formed when arylmethylenebisureas are boiled with sodium borohydride in alcohol.The reaction of benzylidenebisurea with sodium borohydride in DMFA at 160 deg C gives mainly perhydro-2-phenyl-1,3,5-triazine-4,6-dione.
Reactions of urea, thiourea, and related compounds with a number of aldehydes

Benzaldehyde and substituted benzaldehydes react with ureas and thioureas under acid conditions to produce cyclised products, dioxo or dithioxotriazinones (3 and 4).The mechanisms of these reactions has been considered and it is concluded that biuret and
UREAS IN ORGANIC SYNTHESIS X. SYNTHESIS OF PERHYDRO-2-PHENYL-1,3,5-TRIAZINE-4,6-DIONE AND 1,3,5-TRI(METHYLTHIOMETHYL)-1,3,5-TRIAZINE-2,4,6-TRIONE BY THE REACTION OF BENZALDEHYDE WITH UREA OR FROM BENZYLIDENEBISUREA BY THE ACTION OF DIMETHYL SULFOXIDE
Bakibaev, A. A.

Benzaldehyde and urea are converted by the action of DMSO at 185 deg C into benzylidenbisurea and 1,3,5-tri(methylthiomethyl)-1,3,5-triazine-2,4,6-trione.Depending on the reaction temperature, benzylidenebisurea forma either perhydro-2-phenyl-1,3,5-triazi
