Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, the author is Blake, Paul C. and a compound is mentioned, 1271-19-8, Titanocenedichloride, introducing its new discovery. 1271-19-8

Bis(trimethylsilyl)phosphido complexes II. Bis(trimethylsilyl)phosphidobis(tetrahydrofuran)lithium as a reducing agent; X-ray structure of

The lithium compound (THF)2>2 (I) in tetrahydrofuran (THF) under ambient conditions is an effective reducing agent for converting cyclopentadienyl-titanium(IV) or -uranium(IV) chlorides into the corresponding chlorocyclopentadienylmetal(III) complexes.Thus , , and were transformed in high yields into , , and (II), respectively.The crystalline complex II is triclinic, space group P1<*>, with a 11.352(5), b 12.795(7), c 15.o14(7) Angstroem; alpha 101.63(7), beta 90.34(4), gamma 95.92(6) deg, and Z = 2.Its X-ray structure was refined to R1 = 0.056 and R2 = 0.072.The compound is a monomer, with mean U-Cl and Li-Cl bond lengths of 2.730(1) and 2.46(6) Angstroem, respectively; and Cl-U-Cl’, Cl-Li-Cl’, and U-Cl-Li 82.3(2), 94(2), and 91(1) deg, respectively.

Total Synthesis of Gelsemoxonine through a Spirocyclopropane Isoxazolidine Ring Contraction

Plants of the species Gelsemium have found application in traditional Asian medicine for over a thousand years. Gelsemoxonine represents a novel constituent of this plant incorporating a highly functionalized azetidine at its core. We herein report a full account of our studies directed toward the total synthesis of gelsemoxonine that relies on a conceptually new approach for the construction of the central azacyclobutane. A spirocyclopropane isoxazolidine ring contraction was employed to access a key beta-lactam intermediate, which could be further elaborated to the azetidine of the natural product. In the course of our studies, we have gained detailed insight into this intriguing transformation. Furthermore, we report on previously unnoticed oligomerization chemistry of gelsemoxonine. We also document an enantioselective synthesis of a key precursor en route to gelsemoxonine. (Figure Presented).

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 153-94-6!, 1271-19-8
