Compounds formally derived from an
oxoacidRkE(=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
acyl derivatives of
alcohols, etc. Acyl derivatives of chalcogen analogues of
alcohols (
thiols,
selenols, 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
)
(
R
≠
H).
Note:
O-Alkyl derivatives of other acidic compounds [see
amides (1)] may be named as esters but do not belong to the class esters proper. E.g.
(Ph)2POCH3
methyl diphenylphosphinite.
