SYNTHESIS OF SOME IMIDAZO [ I , 2-b] [l , 2,4] TRIAZINE AND N-ALKYLATED IMIDAZO [l , 2-b] [1 , 2,4]-TRIAZINES

A number of 3-amino-1, 2, 4-triazin-5 (2H)- ones(1) were synthesized and condensed with a-haloketones to give 2,6-disubstituted imidazo [1, 2-b] [1, 2, 4]-triazin-3 (4H)-ones (2). These compounds were reacted further with a - haloketones to yield N-alkylated products (3).

A ug 2 00 5 Electronic structure , electron - phonon coupling and superconductivity of isotypic noncentrosymmetric crystals Li 2 Pd 3 B and Li 2 Pt 3

Electronic structure of recently discovered isotypic ternary borides Li2Pd3B and Li2Pt3B, with noncentrosymmetric crystal structures, is studied with a view to understanding their superconducting properties. Estimates of the Fermi-surface averaged electron-phonon matrix element and Hopfield parameter are obtained in the rigid ion approximation of Gaspari and Gyorffy [Phys. Rev. Lett. 28 (1972) ...

SYNTHESIS OF OXAZOLO [3, 2-b] 1, 2, 4- TRIAZINES A NOVEL HETEROCYCLIC SYSTEM

The synthesis of 6- methyl- 2- phenyl- 7H- oxazolo [3,2-b] 1,2,4-Triazine- 7-one (6, R=Ph) and its 2-P- bromophenyl analogue to the two members of a new heterocyclic system is described

Electronic B 2 B Marketplaces - Impact on B 2 B Transactions and Relationships ?

The last two years have seen a rapid development of the use of the Internet in doing economic transactions (E-Commerce). Now that the euphoria has subsided, it is necessary to closely examine which E-Commerce applications will remain and why. Our paper will focus on Electronic B2B Marketplaces. We first define and classify this category of e-commerce and present the value generating models depl...
