“Amidst the Dust” pays homage to the author’s personal experience conducting research for her MA thesis on Italian-American writer John Fante. Her two months spent in Los Angeles—the city where Fante set many of his literary works—were crucial to developing a richer understanding of Fante’s perception of his identity as a son of Italian immigrants.

On the relative strengths of amide…amide and amide…water hydrogen bonds
Chemical Physics Letters, 1991We have performed Hayes—Stone intermolecular perturbation theory (IMPT) calculations on amide…water and amide…amide complexes in order to estimate the change ΔW in intermolecular interaction energy associated with the hydrogen bond exchange process amide(NH)…water+water…(OC)amide⇔amide(NH)…(OC)amide+water…water.

21.1.8 Synthesis of Amides by Transamidation and Amidation of Activated Amides and Esters
2020AbstractThis chapter provides a summary of the recent advances in direct transamidation and amidation reactions of activated amides and esters via transition-metal-catalyzed and transition-metal-free C(acyl) —N and C(acyl) —O bond cleavage as a new disconnection for the synthesis of amide bonds.

Reliable Determination of Amidicity in Acyclic Amides and Lactams
The Journal of Organic Chemistry, 2012Two independent computational methods have been used for determination of amide resonance stabilization and amidicities relative to N,N-dimethylacetamide for a wide range of acyclic and cyclic amides. The first method utilizes carbonyl substitution nitrogen atom replacement (COSNAR).

Flexible and Chemoselective Oxidation of Amides to α-Keto Amides and α-Hydroxy Amides
Journal of the American Chemical Society, 2017A suite of flexible and chemoselective methods for the transition-metal-free oxidation of amides to α-keto amides and α-hydroxy amides is presented. These highly valuable motifs are accessed in good to excellent yields and stereoselectivities with high functional group tolerance.

Amides IX: Acylation of amides and amines
Recueil des Travaux Chimiques des Pays-Bas, 1952AbstractFurther proofs are adduced in favour of the theory of add catalyzed acylation of amides to diacylamines. Synthetic examples are given partly as improvements of older methods, partly as illustrations of the theory. The preparation of the following new compounds is described: N‐isobutyrylbenzamide, N‐acetyl‐n‐butyramide, N‐methyldipropionimide ...
