O-(1-Methyl-2-methoxycarbonylvinyl) 4-Bromophenylthionophosphonic monochloride is another example where I get confused, I thought the O- should indicate that there is a P-ester, but I get a trivalent Cl
CC(=CC(=O)OC)[ClH]P(O)(=O)C1=CC=C(C=C1)Br
I was hoping for:
CC(=CC(=O)OC)OP(Cl)(=O)C1=CC=C(C=C1)Br
from opsin.
Another example - this one ChemDraw gets what I expect:
phenyl (benzyloxy-glycinyl)-phosphorochloridate
Opsin gives:
C(C1=CC=CC=C1)ONCC(=O)[ClH]P(OC1=CC=CC=C1)([O-])=O
ChemDraw:
O=P(OC1=CC=CC=C1)(Cl)OC(CNOCC2=CC=CC=C2)=O

I presume you meant CC(=CC(=O)OC)OP(Cl)(=S)C1=CC=C(C=C1)Br ?

This example is more difficult to fix. In the first two cases conceptually the OH groups have already been substituted so definitely cannot be turned into chlorine, but in this example strictly speaking we're substituting phosphorochloridate which is P([O-])([O-])(=O)Cl
. phenyl (benzyloxy-glycinyl) phosphorochloridate
gives the expected interpretation

Thanks Daniel.
Yes, obviously meant the sulfur analog.
So, in phenyl (benzyloxy-glycinyl)-phosphorochloridate there is a bonus '-', as that should be rather rare I can add it to one of our dictionaries.
