Solvent dependent reductive defluorination of aliphatic C-F bonds employing Sm(HMDS)2.
Chem. Commun. (Camb.) 49(18) , 1826-8, (2013) Sm(HMDS)(2) in n-hexane mediates fast cleavage of primary, secondary and tertiary alkyl fluorides in good to excellent yields. In n-hexane Sm(HMDS)(2) exhibits uniquely enhanced reductive ability towards the C-F bond compared to when using THF as solvent. |

Evidence for supernova injection into the solar nebula and the decoupling of r-process nucleosynthesis.
Proc. Natl. Acad. Sci. U. S. A. 110(43) , 17241-6, (2013) The isotopic composition of our Solar System reflects the blending of materials derived from numerous past nucleosynthetic events, each characterized by a distinct isotopic signature. We show that the isotopic compositions of elements spanning a large mass ra... |
