O-Phenyl (tert-butylamido)(p-tolylamido)phosphinate
In the title mol-ecule, C(17)H(23)N(2)O(2)P, the P atom has a distorted tetra-hedral environment. The P-N bond to the tolyl-amido fragment is 1.642 (4) Å while that to the butyl-amido fragment is 1.629 (3) Å. The dihedral angle between the two benzene rings is 82.3 (2)°. In the crystal, adjacent mol-ecules are linked via weak N-H⋯(O)P and N-H⋯N hydrogen-bonding inter-actions into an extended ch...

The title compound, [Li(2)(C(9)H(14)N)(C(16)H(36)P(3))](n), is a by-product of the reaction of [Cp(C(5)H(4)CH(2)CH(2)NMe(2))ZrCl(2)](n) with (t)Bu(2)P-P(SiMe(3))Li in toluene. It is a coordination polymer composed of infinite chains running along [010]. One Li(I) atom is chelated by the cyclo-penta-dienyl ring and and the N atom of the scorpionate ligand and a P atom, whereas the other Li(I) at...
متن کاملPyrene-p-tert-butylcalixarenes inclusion complexes formation: a surface photochemistry study.
Diffuse reflectance and luminescence techniques were used to study the photophysics and photochemistry of pyrene within p-tert-butylcalix[n]arenes with n = 4, 6, and 8, and to study their ability to form inclusion complexes in heterogeneous media. Evidences for inclusion complex formation were found for the three hosts under study. Ground state diffuse reflectance results have shown the formati...
متن کاملP. berghei Telomerase Subunit TERT is Essential for Parasite Survival
Telomeres define the ends of chromosomes protecting eukaryotic cells from chromosome instability and eventual cell death. The complex regulation of telomeres involves various proteins including telomerase, which is a specialized ribonucleoprotein responsible for telomere maintenance. Telomeres of chromosomes of malaria parasites are kept at a constant length during blood stage proliferation. Th...
متن کامل2-(4-tert-Butylphenyl)-5-p-tolyl-1,3,4-oxadiazole
In the title compound, C(19)H(20)N(2)O, the dihedral angles between the 1,3,4-oxadiazole ring and the pendant 4-tert-butyl-phenyl and 4-methyl-phenyl rings are 12.53 (17) and 2.14 (17)°, respectively. In the crystal, mol-ecules are linked by C-H⋯N hydrogen bonds, forming chains.
