The [BAr F 4] − anion with four fluorinated aryl groups distributed tetrahedrally about a central boron atom. Tetrakis[3,5-bis(trifluoromethyl)phenyl]borate is an anion with chemical formula [{3,5-(CF 3) 2 C 6 H 3} 4 B] −, which is commonly abbreviated as [BAr F 4] −, indicating the presence of fluorinated aryl (Ar F) groups.
Bis(trimethylsilyl)acetamide (BSA) is an organosilicon compound with the formula MeC(OSiMe 3)NSiMe 3 (Me = CH 3). It is a colorless liquid that is soluble in diverse organic solvents, but reacts rapidly with moisture and solvents containing OH and NH groups .
The numbers 200-900 would be confused easily with 22 to 29 if they were used in chemistry. khīlioi = 1000, diskhīlioi = 2000, triskhīlioi = 3000, etc. 13 to 19 are formed by starting with the Greek word for the number of ones, followed by και (the Greek word for 'and'), followed by δέκα (the Greek word for 'ten').

Bis(pinacolato)diboron is a covalent compound containing two boron atoms and two pinacolato ligands. It has the formula [(CH 3) 4 C 2 O 2 B] 2; the pinacol groups are sometimes abbreviated as "pin", so the structure is sometimes represented as B 2 pin 2. It is a colourless solid that is soluble in organic solvents.

Bis(oxazoline) ligands (often abbreviated BOX ligands) are a class of privileged chiral ligands containing two oxazoline rings. They are typically C 2 ‑symmetric and exist in a wide variety of forms; with structures based around CH 2 or pyridine linkers being particularly common (often generalised BOX and PyBOX respectively).
Diradicals are usually triplets.The phrases singlet and triplet are derived from the multiplicity of states of diradicals in electron spin resonance: a singlet diradical has one state (S=0, M s =2*0+1=1, m s =0) and exhibits no signal in EPR and a triplet diradical has 3 states (S=1, M s =2*1+1=3, m s =-1; 0; 1) and shows in EPR 2 peaks (if no hyperfine splitting).
