Cyclopropenes in Photochemical Reactions

open access: yesChemistry – A European Journal, Volume 32, Issue 3, 16 January 2026.
The photochemical side of cyclopropenes. Cyclopropenes are valuable synthetic tools in organic chemistry. In particular, this review focuses on the photochemistry of cyclopropenes. The reactivity of cyclopropenes excited by irradiation is discussed showing their unique potential for organic synthesis.

Preparation of organic hydrazides [PDF]

open access: yes, 1959
Thesis (M.A.)--Boston UniversityDue to the actual high price of hydrazine, this chemical cannot be used in an economical preparation of organic hydrazides. A synthesis of such hydrazides can be envisaged by the reduction of N-nitroamides.

Multiphase detection of crucial biological amines using a 2,4,6-tristyrylpyrylium dye

open access: yesCommunications Chemistry
The strong electrophilicity of arylpyrylium salts was recognized for the colorimetric detection of vital amine analytes, limited to ammonia or methylamines and putrescine as biogenic amine.

Isolation and characterization of Methanosphaera sp. ISO3-F5, a member of a novel and widespread species of rumen methanogens growing with methanol plus hydrogen

open access: yesThe Microbe
Rumen methanogens predominantly fall into two physiological groups: hydrogenotrophs which use hydrogen (H2) to reduce carbon dioxide (CO2) to methane (CH4), and methylotrophs which use H2 to reduce methanol and methylamines as substrates for ...
