Abstract (en)
[origin: DE19647584A1] Palladaphosphacyclobutanes are disclosed having the formula (I), in which R<1>, R<2> independently represent hydrogen, (C1-C4)-alkyl, (C3-C12)-cycloalkyl, (C1-C4)-alkoxy, fluorine, N(alkyl)2-C(C1-C4-alkyl, OCO-alkyl-(C1-C4) or aryl; R<3>, R<4>, R<5>, R<6> independently represent (C1-C8)-alkyl, (C3-C12)-cycloalkyl or aryl; or in which R<1> and R<2>, R<1> or R<2> and R<3> or R<4>, R<3> and R<4>, R<3> or R<4> and R<5> or R<6>, or R<5> and R<6> form together an aliphatic ring; or in which R<5> and R<6>, R<3> or R<4> and R<5> or R<6> form together an aromatic ring; and Y stands for an anion of an inorganic or organic acid, except for the compounds di- mu -chloro-bis[2-[bis(1,1-dimethylethyl)phosphino]-2-methylpropyl-C,P]dip alladium (II), di- mu -bromo-bis[2-[bis(1,1-dimethylethyl)phosphino]-2-methylpropyl-C,P]dipa lladium (II), di- mu -trifluoroacetato-bis[2-[bis(1,1-dimethylethyl)phosphino]-2-methylprop yl-C,P]dipalladium (II), di- mu -chloro-bis[2-[(1,1-dimethylethyl)phénylphosphino]-2-methylpropyl-C,P] dipalladium (II), mu -chloro- mu -methoxy-bis[2-[bis(1,1-dimethylethyl)phosphino]-2-methylpropyl-C,P]di palladium (II).
