How is arsanylidynethulium (CAS: 12056-07-4) typically synthesized?

Arsanylidynethulium is typically synthesized through the reaction of ruthenium hydride with thulium trichloride in an inert atmosphere. The process involves the use of a metal catalyst to enhance the reactivity and yield. The product is obtained in high yield with good selectivity, but the reaction conditions must be carefully controlled to avoid side reactions.
