4 Metalorganic and Metalloidorganic Compounds
a) Cyclopentadienylcaesium
b) Caesium cyclopentadienide
For the less polar organic derivatives of the alkaline earth metals (with the
exception of Grignard compounds) method a) is applied exclusively.
Bis(pentafluorophenyl)magnesium
Bis( triphenylmethyl)calcium
Dimethylbarium
Metalorganyls of the Grignard compound type, however, are predominantly named as hemi salts according to a hybrid procedure based on
method a) - if coordination names are not preferred outright.
Phenylmagnesium iodide
Iodo(phenyl)magnesium
Methylmagnesium hydride
Hydridomethylmagnesium
t-Butylstrontium bromide
t- Butylbromostrontium
Triphenylmethylcalcium chloride
Chloro( triphenylmethyl) calcium
It is immediately apparent that analogous organic derivatives of transition
metals can be named in exactly the same manner:
t-Bu
.Bu-Q-AUCI,
t-Bu
Phenylethynylsilver
(2,4,6-Tris-t-butylphenyl)gold dichloride
Dichloro( tri -t-butylphenyl)gold
why not:
Dichloro( tri -t-butylphenyl)-.. P-aurane
