Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 13035-61-5, Name is Beta-D-Ribofuranose 1,2,3,5-tetraacetate, molecular formula is , belongs to benzodioxans compound.

SYNTHESIS AND NMR-SPECTROSCOPY OF PHOSPHORANES WITH 1,3,2-DIOXA-4,5-NAPHTHOPHOSPHOLE RING
The reaction of naphthalene-2,3-diol 1 with PCl3 was found to furnish the hydridophosphorane 3, with PCl5 the chlorophosphorane 4 was formed. The reaction of the fluorophosphoranes, RPF4 [R=F, (i)Pr, CH2SiMe3, CH2Cl, Ph] with the bis(trimethylsilyl) derivative of 1, 2 yielded the corresponding spirocyclic phosphoranes, 5-9 by cleavage of the Si-O bond and elimination of Me3SiF. The difluorophosphoranes, R2PF3 [R=Me, Ph] reacted with 2 to form the monocyclic phosphoranes, 10 and 11, where the fluorine atom occupies an axial position at trigonal-bipyramidal (TBP) phosphorus- The structure of compound 11 was confirmed by single crystal X-ray analysis of its dichloromethane hemisolvate at -95-degrees-C. The geometry at phosphorus is trigonal-bipyramidal. whereby the naphthalenedioxy ligand spans an axial and an equatorial site. Me2PF3 reacted with tetrakis(1,2,4.5-trimethylsiloxy)benzene to form the bifunctional benzodioxa-lambda5-phosphole, 12.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 13035-61-5, in my other articles.
