N-Chloramidophosphate / N-Chlorophosphoramidates

Abstract

<jats:p>The structure of the known compound O,O-Diphenyl-N-chlorophosphoramidate has been determined by X-ray diffraction. It consists of dimers, in which the monomers are connected by N-H···O hydrogen bonds. The O,O-Diethyl-N-chlorophosphoramidate homologue can be synthesized by various methods. At room temperature it is part of an equilibrium mixture with O,O-Diethyl-phosphoramidate and O,O-Diethyl-N,N-dichloro-phosphoramidate.</jats:p>

Conformational flexibility in amidophosphoesters: a CSD analysis completed with two new crystal structures of (C6H5O)2P(O)X [X = NHC7H13 and N(CH2C6H5)2]

“…In (I), the angle between the planes of the phenyl rings is 26.1 (3) and the torsion angles of À178.2 (4) for C3-O2-P1-O10 and À179.7 (4) for C11-O10-P1-O2 define the Àap conformation for phenyl rings 1 and 2, as noted. The 14 molecules ZIFYIW-Mol1 (Aparna et al, 1995), LEQRIK01-Mol2 (Gholivand et al, 2013), YEVSAT (Herrmann et al, 1994), FIBROY-Mol1 (Gholivand et al, 2005), OFESEZ-Mol2 (Safin et al, 2013), BIFYUN (Das et al, 2018), BIFXIA-Mol1 (Das et al, 2018), BOGPOC (Drewelies & Pritzkow, 1982), UREDUR-Mol1 (Sabbaghi et al, 2011b), KAVVAE-Mol1 (Zá k et al, 1989), SOYCUE-Mol1 (Richter et al, 1991), SOYCUE-Mol2 (Richter et al, 1991), OFESAV-Mol1 (Safin et al, 2013) and WIBKUN-Mol1 (Rebrova et al, 1993) adopt a similar conformation (Àap and Àap) and their phenyl rings are similar to those in (I) ( Fig. 5b and Table S3 in the supporting information).…”
