متن کاملSYNTHESIS 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 radio-access solution was sought because it would eliminate the need for cables and overcome lineof-sight restrictions. It was also recognized that a low-cost solution would usher in wireless connectivity for a multitude of new applications ...
متن کاملProperties of L=1 B(1) and B(2)* mesons.
This Letter presents the first strong evidence for the resolution of the excited B mesons B(1) and B(2)* as two separate states in fully reconstructed decays to B(+)(*)pi(-). The mass of B(1) is measured to be 5720.6+/-2.4+/-1.4 MeV/c(2) and the mass difference DeltaM between B(2)* and B(1) is 26.2+/-3.1+/-0.9 MeV/c;{2}, giving the mass of the B(2)* as 5746.8+/-2.4+/-1.7 MeV/c(2). The productio...
