A one-pot deamination of a wide variety of substituted anilines is described. The process involves a diazotization-dediazotization utilizing acetic acid, sodium nitrite, and sodium bisulfite- inexpensive, ‘green’ reagents. The process occurs quickly under mild conditions, tolerates sensitive functionality, and gives products in modest-to-good yields (16–88%).
In order to illustrate the different nature of the magnetism underlying the two magnetic hyperfine fields in α-Mn, we present measurements in applied magnetic fields and at various temperatures. It was concluded that one hyperfine field is due to a local-moment antiferromagnetism and the other exhibits features related to the existence of a spin density wave (SDW).
We present a case of dramatic response of poor prognosis cancer in a lady with a germline mutation in the BRCA2 gene who was Ghd Straighteners Amazon Uk
exposed to platinum containing chemotherapy. She is cancer-free 10 years’ later. Such cases Cheap Babyliss Uk
provide clinical scenarios for the basis of trials of platinum-like agents in individuals with BRCA mutations who develop cancer.
In this paper, we first establish a second main theorem for algebraic curves into the n -dimensional projective space. We then use it to study the ramified values for the Gauss map of the complete (regular) minimal surfaces in RmRm with finite total curvature, as well as the uniqueness problem.
