OXYDES ET SULFURES DE BIS (OU TRIS)(AMIDINO)PHOSPHINES: SYNTHESE ET CYCLISATION EN 2-OXO (OU THIO)2,5-DIHYDRO-1,3,5,2lambda5-TRIAZAPHOSPHININES
The title compounds R13-nP(X)(N=C(R2)NH2)n (n=2,3; X=O,S) are obtained by the reaction of unsubstituted amidines R2-C(=NH)-NH2 with oxo (or thio)trichloro or organyldichlorophosphines.Isolated compounds 1 (R2=Ph) lead, with heating, to the 2-oxo (or thio) 2,5-dihydro-1,3,5,2lambda5-phosphinines 2.Compounds 1, with R2=alkyl are unstable, and lead directly to 2.P(NMe2)3 reacts with amidines in a molar ratio of 1:2 to give the 2,5-dihydro-1,3,5,2lambda3-triazaphosphinines 4; from these latter derivatives we tried unsuccessfully to prepare the corresponding dicoordinated phosphorus derivatives 7. Key words: Oxo (or thio) bis (or tris)(amidino)phosphines; 2,5-dihydro-1,3,5,2lambda5(or lambda3)-triazaphosphinines.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1608-26-0, help many people in the next few years., Reference of 1608-26-0
