Reactions of Atomic Carbon with Acid Chlorides
1his thesis is the flfst report of reactions of atomic calbon with acid chlorides. Carbon is known to react with phosgene to afford dichlorocarbene. We report a similar reaction with carbon and acid ch~lorides, generating alkylchlorocarbenes. We examine both the nature of the carbene products generated through deoxygenation and the general reacliviry ofcarbon with the acid chlorides. We report ...
متن کاملOn Some New Color Reactions of Cholesterol
In the course of some investigations on the function of cholesterol in the animal body, the results of which will be reported at a later time, I found that cholesterol was readily soluble in quite a number of anhydrous inorganic chlorides and bromides. Among these solvents are the following: PCl,, AsC&, AsBr3, SbC13, SnCL, Sic&, SiBra, Tic&, SOC12, POCl,, SeOC&, and CBr4. Since colorless soluti...
متن کاملReactions of an Isolable Dialkylsilylene with Aroyl Chlorides. A New Route to Aroylsilanes.
The reactions of isolable dialkylsilylene 1 with aromatic acyl chlorides afforded aroylsilanes 3a-3c exclusively. Aroylsilanes 3a-3c were characterized by ¹H-, 13C-, and 29Si-NMR spectroscopy, high-resolution mass spectrometry (HRMS), and single-crystal molecular structure analysis. The reaction mechanisms are discussed in comparison with related reaction of 1 with chloroalkanes and chlorosilanes.
متن کاملSynthesis and chemical reactions of the steroidal hormone 17α-methyltestosterone.
Structural modifications of natural products with complex structures like steroids require great synthetic effort. A review of literature is presented on the chemistry of the steroidal hormone 17α-methyltestosterone that is approved by Food and Drug Administration (FDA) in the United States as an androgen for estrogen-androgen hormone replacement therapy treatment. The analog also offers specia...
متن کاملHigh stereoselectivity in chelation-controlled intermolecular Heck reactions with aryl chlorides, vinyl chlorides and vinyl triflates.
Highly stereoselective chelation-controlled Pd(0)-catalyzed beta-arylations and beta-vinylations of a five-membered chiral, pyrrolidine-based vinyl ether were achieved using aryl- and vinyl chlorides as substrates, yielding quaternary 2-aryl/vinyl-2-methyl cyclopentanones in 89-96% ee under neutral reaction conditions.
