(a) Structure of a hexagonal TMD monolayer. M atoms are in black and X atoms are in yellow. (b) A hexagonal TMD monolayer seen from above. Transition-metal dichalcogenide (TMD or TMDC) monolayers are atomically thin semiconductors of the type MX 2, with M a transition-metal atom (Mo, W, etc.) and X a chalcogen atom (S, Se, or Te).
MoS 2, the most common metal dichalcogenide, adopts a layered structure. Metal dichalcogenides have the formula ME 2, where M = a transition metal and E = S, Se, Te. [7] The most important members are the sulfides. They are always dark diamagnetic solids, insoluble in all solvents, and exhibit semiconducting properties. Some are superconductors ...

Niobium diselenide or niobium(IV) selenide is a layered transition metal dichalcogenide with formula NbSe 2.Niobium diselenide is a lubricant, and a superconductor at temperatures below 7.2 K that exhibit a charge density wave (CDW).
During annealing, self-assembly of the amorphous precursors takes place, resulting in crystallization within the layer plane. This non-epitaxial growth method leads to the formation of abrupt interfaces and in-plane crystallinity and enables nearly arbitrary stacking sequences of transition metal dichalcogenides and metal mono chalcogenides.

Tungsten ditelluride has layered structure, similar to many other transition metal dichalcogenides, but its layers are so distorted that the honeycomb lattice many of them have in common is in WTe 2 hard to recognize. The tungsten atoms instead form zigzag chains, which are thought to behave as one-dimensional conductors.
Concerted metalation-deprotonation (CMD) is a mechanistic pathway through which transition-metal catalyzed C–H activation reactions can take place. In a CMD pathway, the C–H bond of the substrate is cleaved and the new C–Metal bond forms through a single transition state. [1]
