In the C(O)NHP(O) fragment of the title compound, C(35)H(32)F(2)N(3)O(2)P, the P-N bond is longer and the O-P-N angle is contracted compared with the other two P-N bonds and O-P-N angles. The P atom adopts a distorted tetra-hedral environment and the phosphoryl and carbonyl groups are anti with respect to each other. The two tertiary N atoms of the dibenzyl-amido groups show sp(2) character wit...

In the title mol-ecule, C(15)H(17)ClN(2)O(2), the furan and benzene rings form a dihedral angle of 15.35 (8)°. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains extended in the [010] direction.

The title compound, C(22)H(31)NO, has been synthesized from 4-bromo-methyl-2,6-di-tert-butyl-phenol and N-methyl-aniline. There are two independent mol-ecules in the asymmetric unit. The aniline ring in each of the independent mol-ecules was found to be disordered, with site occupation factors 0.621 (10)/0.379 (10) and 0.605 (10)/0.395 (10).

In the salt, C(7)H(16)N(+)·C(16)H(28)F(3)N(3)O(2)P(-), the P atom shows tetra-hedral coordination. Two ion pairs are linked by N-H⋯O hydrogen bonds across a center of inversion. The phosphoryl and carbonyl groups are staggered [O-P-N-C = 64.8 (3)°].

tetra-n-butyl ammonium hydroxide was used as a catalyst for one-pot, three component condensation reactions consisting of aromatic aldehydes, malononitrile and barbituric acid in ethanol:water solvent system at 60oc. current method has major advantages like mild reaction conditions with simple operation, high yields, by using a less toxic and lower costlier catalyst.in conclusion, we have explo...
