The formation of formates: a review of metal formates on heritage objects [PDF]

open access: yesHeritage Science, 2021
Metal formates sometimes occur as degradation products on heritage objects due to the use of wood products or other sources of formic acid and formaldehyde.

On the Gas-Phase Interactions of Alkyl and Phenyl Formates with Water: Ion–Molecule Reactions with Proton-Bound Water Clusters [PDF]

open access: yesMolecules, 2023
Ion–molecule reactions between the neutral ethyl- (EF), isopropyl- (IF), t-butyl- (TF) and phenyl formate (PF) and proton-bound water clusters W2H+ and W3H+ (W = H2O) showed that the major reaction product is water loss from the initial encounter complex,

Achievements and challenges in deciphering heterogeneous catalytic reaction mechanisms using operando infrared spectroscopies [PDF]

open access: yesNature Communications
In situ / operando infrared spectroscopy is commonly used to investigate heterogeneous catalytic reactions. Adsorbates, such as carbonyl and formates, present under reaction conditions can be monitored and quantitative infrared techniques enable ...

Generation of Formates Following 20 kHz Sonication of DSPE-mPEG2000 PEGylated Phospholipid Micelles [PDF]

open access: yesPharmaceutics
Background: Previous research has demonstrated that 20 kHz probe or 37 kHz bath sonication of poloxamers comprising polypropylene glycol (PPG) and polyethylene glycol (PEG) blocks can generate degradation byproducts that are toxic to mammalian cells and ...

Palladium-Catalyzed Esterification of Aryl Fluorosulfates with Aryl Formates [PDF]

open access: yesMolecules
An efficient palladium-catalyzed carbonylation of aryl fluorosulfates with aryl formates for the facile synthesis of esters was developed. The cross-coupling reactions proceeded effectively in the presence of a palladium catalyst, phosphine ligand, and ...

Racial formations as data formations [PDF]

open access: yesBig Data & Society, 2021
This commentary uses Paul Gilroy’s controversial claim that new technoscientific processes are instituting an ‘end to race’ as a provocation to discuss the epistemological transformation of race in algorithmic culture. We situate Gilroy’s provocation within the context of an abolitionist agenda against racial-thinking, underscoring the relationship ...

Starch Formates: Synthesis and Modification

open access: yesMolecules, 2021
Starch can be efficiently converted into the corresponding formates homogeneously using N-formyl imidazole obtained by the reaction of 1,1′-carbonyldiimidazole and formic acid in dimethyl sulfoxide as a solvent.

Glycosyl Formates: Glycosylations with Neighboring-Group Participation

open access: yesMolecules, 2022
Protected 2-O-benzyolated glycosyl formates were synthesized in one-step from the corresponding orthoester using formic acid as the sole reagent.

Thermal Decomposition of [AH][M(HCOO)3] Perovskite-Like Formates

open access: yesSolids, 2021
A systematic study of the thermal decomposition of hybrid perovskites of formula [AH][M(HCOO)3] under inert atmosphere was performed by means of thermogravimetry and simultaneous infrared spectroscopy of the evolved gases. The influence of: (i) the metal
