    N,N--Dibenzyl-N--(2-chloroacetyl)-N,N--dimethylphosphoric triamide 

    Type: Journal Paper
    Author : مهرداد پورایوبی; مجتبی کیخا; Marek Nečas; Mehrdad Pourayoubi; MOJTABA KEIKHA
    Year: 2011
    Abstract:

    In the title molecule, C18H23ClN3O2P, the P atom is bonded in a distorted tetrahedral environment. The P=O and N—H groups are syn with respect to each other. The angles at the tertiary N atoms confirm their sp2 character. ...

    N,N--Dibenzyl-N,N--dimethyl-N---(2-phenylacetyl)phosphoric triamide 

    Type: Journal Paper
    Author : مهرداد پورایوبی; صمد شوق پوربیرق; Laura Torre-Fernández; Santiago Garcıa-Granda; Mehrdad Pourayoubi; samad shoghpour bayraq
    Year: 2011
    Abstract:

    The P atom in the title molecule, C24H28N3O2P, is in a distorted tetrahedral P(=O)(N)(N)2 environment. The phosphoryl group and the NH unit adopt a syn orientation with respect to each other and the N atoms have sp2 ...

    N,N -Dicyclohexyl-N -(4-nitrobenzoyl)- phosphoric triamide 

    Type: Journal Paper
    Author : Fahimeh Sabbaghi; مهرداد پورایوبی; Maryam Toghraee; Vladimir Divjakovic; Mehrdad Pourayoubi
    Year: 2010
    Abstract:

    The P atom in the title compound, C19H29N4O4P, exhibits a

    tetrahedral coordination and the phosphoryl and carbonyl

    groups are anti to each other. Adjacent molecules are linked

    by N—H O hydrogen bonds ...

    Bis(pyrrolidin-1-yl)phosphinic (2,4-difluorobenzoyl) amide 

    Type: Journal Paper
    Author : مجتبی کیخا; مهرداد پورایوبی; Jerry P. Jasinski; James A. Golen; MOJTABA KEIKHA; Mehrdad Pourayoubi
    Year: 2012
    Abstract:

    The P atom in the title molecule, C15H20F2N3O2P, is in a distorted tetrahedral P(O)(N)(N)2 environment. The phosphoryl group and the NH unit adopt a syn orientation with respect to each other. An F atom at position 2 and ...

    5Amino-3-methyl-1,2-oxazole-4-carbo- nitrile 

    Type: Journal Paper
    Author : صمد شوق پوربیرق; امیر کیخا; Hadi Amiri Rudbari; محمد رحیمی زاده; مهدی بکاولی; مهرداد پورایوبی; Francesco Nicolò; samad shoghpour bayraq; Amir Keykha; Mohammad Rahimizadeh; Mehdi Bakavoli; Mehrdad Pourayoubi
    Year: 2012
    Abstract:

    In the title compound, C5H5N3O, the isoxazole ring is essentially planar, with a maximum deviation of 0.007 (1) Å from the least-squares plane. The N atom of the amine group exhibits sp2 character (sum of bond angles around ...
