Hydrogen Bond Influence on Physical Properties of p-n-Propyloxybenzoic Acid – p-n-Propyloxy-p'-Cyanobiphenyl System

REACTIVITY OF N-SUBSTITUTED p-BENZO AND p-NAPHTHOQUINONEIMINE N-OXIDES TOWARD DIPOLAROPHILES

The dipolar cycloaddition reactivity of N-(1-naphthy1)-1,4- benzoquinoneimine N-oxide and N-phenyl-1,4- naphthoquinoneimine Noxide are investigated, The latter gives the expected adducts with common dipolarophiles such as acrylonitryle, methyl methacrylate, dimethylacetylene dicarboxylate and N-phenylmaleimide. The reactivity of the former nitrone is found to be minimal. It undergoes, how...

φ: P n �� � (P 1) n+1

We develop in this paper some methods for studying the implicitization problem for a rational map φ : Pn 99K (P1)n+1 defining a hypersurface in (P1)n+1, based on computing the determinant of a graded strand of a Koszul complex. We show that the classical study of Macaulay Resultants and Koszul complexes coincides, in this case, with the approach of approximation complexes and we study and give ...

Failure of P-(di-n-propylsulfamyl)-benzoic acid (benemid) to influence p-aminosalicylic acid blood levels.

N,P,P-Triisopropyl­phosphinic amide

The title compound, C(9)H(22)NOP, was obtained by slow diffusion of oxygen into a toluene solution of (i)Pr(2)PNH(i)Pr. In the crystal, an inter-molecular N-H⋯O hydrogen bond occurs.
