Unlocking Stereodefined Olefins by Z‐Selective Transition Metals‐catalyzed C−H Activations
The synthesis of Z‐olefins is an important challenge in synthetic organic chemistry. Within this review, we report a comprehensive overview of transition metals‐catalyzed Z‐selective C–H activations of (hetero)arenes for the synthesis of stereodefined olefins.

A new family of pentamethylcyclopentadienyl (C5Me5, Cp*) iridium(III), rhodium(III), and ruthenium(III) complexes bearing bidentate 1,2‐dioxime ligands was developed and their catalytic performances were evaluated in the hydrogen‐borrowing‐type H/D exchange of amines using D2O as both solvent and deuterium source. Iridium derivatives achieved excellent

Guava leaf essential oil (GL‐EO) and Oliveria decumbens essential oil (Od‐EO) improved the microbial and oxidative stability of refrigerated ground beef and helped extend its shelf life. GL‐EO better preserved odor and color, while the combined GL‐EO + Od‐EO treatment provided the best texture preservation and highest overall acceptability.

Volatile oils were extracted from the fruit and stem of Wurfbainia villosa by steam distillation, with yields of 1.87% for the fruit and 0.13% for the stem. GC–MS analysis identified 46 compounds in the fruit oil and 59 compounds in the stem oil, with 27 common components, 19 unique to the fruit, and 32 unique to the stem.

Parsley (Petroselinum crispum) was harvested at four ontogenetic stages (Pet‐1 to Pet‐4; May–September) under Mediterranean field conditions. Harvest timing significantly affected both agronomic yield and essential oil (EO) composition. Biomass yield peaked at Pet‐4 (10,076 kg da−1); EO content was highest at Pet‐2 (0.70%). GC–MS identified 55 volatile
