esters

https://doi.org/10.1351/goldbook.E02219
Compounds formally derived from an @O04374@ RkE(=O)l(OH)m, (l ≠ 0) and an alcohol, phenol, heteroarenol, or enol by linking with formal loss of water from an acidic hydroxy group of the former and a hydroxy group of the latter. By extension @A00123@ derivatives of @A00204@, etc. Acyl derivatives of chalcogen analogues of @A00204@ (@T06359@, @S05574@, tellurols) etc. are included. E.g. R'C(=O)(OR) , R'C(=S)(OR) , R'C(=O)(SR) , R'S(=O)2(OR) , (HO)2P(=O)(OR) , (R'S)2C(=O) , ROCN (but not R–NCO) (RH).

Note:
O-Alkyl derivatives of other acidic compounds [see @A00266@] may be named as esters but do not belong to the class esters proper. E.g. (Ph)2POCH3 methyl diphenylphosphinite.
