    Description / Table of Contents: Photochemische Reaktionen von 1-Alkyl-4,6-diaryl-2(1H)-pyrimidinonen in Gegenwart von AminenBei Bestrahlung der 1-Alkyl-4,6-diaryl-2(1H)-pyrmidinone 1 unter Zusatz von aliphatischen Aminen wurden die C—C-gebundenen 1:1-Addukte und/oder die reduzierten Dihydropyrimidinone erhalten, wogegen 1 unter Zusatz von aromatischen Aminen ausschließlich die 1:1-Addukte ergab. Die Photoadditionen Aminen an 1 können durch einen stufenweisen Elektronen/Protonen-Übertragungsmechanismus erklärt werden.
    Notes: Irradiation of 1-alkyl-4,6-diaryl-2(1H)-pyrimidinones 1 in the presence of aliphatic amines gave the C—C-bonded 1:1 adducts and/or the reduced dihydropyrimidinones, while irradiation of 1 in the presence of aromatic amines gave the 1:1 adducts exclusively. The photoadditions of amines to 1 can be explained by a sequential electron/proton transfer mechanism.
