John R. Shillady letter to Warren G. Harding, February 18, 1920
No full textIn this letter dated February 18, 1920, John H. Shillady, secretary at the National Association for the Advancement of Colored People (NAACP), writes to Senator Warren G. Harding in regards to Harding's stances on important issues. The NAACP publishes the views of all presidential candidates, and asks Harding to answer seven questions that are important to the organization. The questions relate to Harding's stance on anti-lynching laws, disfranchisement of African Americans, Jim Crow laws, America's military presence in Haiti, discrimination in education, the appointment of African American military officers, and abolishing segregation.
This letter is part of the Warren G. Harding Papers (MSS 345). This collection includes correspondence, business records, and other materials documenting Harding’s business career as owner and editor-in-chief of The Daily Marion Star, as well as the various stages of his political career. A significant portion of the collection, and what’s available on Ohio Memory, highlights his 1920 presidential campaign, spanning just before publicly announcing his candidacy to handily defeating Ohio Governor James M. Cox in the election. Correspondents include both Ohio and national businessmen, political figures, and ordinary citizens writing with questions, support, congratulatory notes, and campaign advice. Some of the most interesting insights into the tumultuous political climate in the U.S., the extreme factionalism within the Republican Party in Ohio, and Harding’s campaign strategies are described in letters between Harding and his campaign manager, Harry M. Daugherty. Some of the topics addressed include women’s suffrage, Prohibition, the League of Nations, African American representation and issues, and lingering peace negotiations following World War I

A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
Mechanistic Insights into Copper Catalyzed sp3 C-H Functionalization
No full textPh.D.Direct C-H functionalization offers opportunities to modify carbon centers normally inert to traditional methods that rely on functional group manipulations, diversifying methods for complex organic molecule synthesis. Traditional synthetic methods often require activated carbon centers. For instance, the most common organic route to C-N bond formation is the nucleophilic substitution of R-X (X = halide, activated-OH) or reductive amination of carbonyl functional groups, R1COR2. Similarly, in C-O and C-C bond formation, a nucleophilic functional group attacks an electrophilic carbon. More economical and efficient C-N, C-O, and C-C bond formation would directly aminate C-H bonds with corresponding functional groups, H-NR1R2, H-OR’, and H-CH2E (E = C(O)R or NO2). The use of transition metal catalysts can allow such transformations for even relatively strong sp3-C-H bonds. The development of such selective transformations, however, is still in its infancy. Though many mechanisms have been proposed for transition metal catalyzed C-H functionalization, few are well understood. Thus, improved mechanistic insights can lead to more rapid advancements in synthetic methodologies.Herein we describe the mechanistic understanding of -diketiminato copper(I) complexes, [CuI], in catalytic intramolecular sp3 C-H functionalization using tBuOOtBu as an oxidant. With initial success in C-H amination using unactivated alkyl and arylamines, H-NR1R2, each step in the proposed catalytic cycle underwent rigorous analysis, largely devoted to understanding the role of -diketiminato copper(II) amide intermediates [CuII]-NR1R2. Previous studies proposed [CuII]-NHAd (Ad = adamantyl) as the intermediate responsible for a key step in our catalysis, capable of performing both hydrogen atom abstraction (HAA) of R-H to give R as well as radical capture (RC) of this alkyl radical R to give R-NHAd and [CuI]. With other copper(II) amides bearing aromatic N-substituents, the role of such [CuII]-NHAr species is primarily to capture the R radical formed via HAA of R-H by •OtBu (released by [CuI] catalyzed homolytic cleavage of tBuOOtBu). This amino variant Kharasch-Sosnovsky reaction has been effectively applied to other functional groups such as alcohols, nitroalkanes, and aryl ketones to introduce new methods for sp3-C-O and sp3-sp3 C-C bond formation
