1. A process comprising the process steps of:
a) initially charging an ethylenically unsaturated compound;
b) adding a ligand of formula (I):
![]() wherein
R1, R2 and R3 are selected from the group consisting of —(C1-C12)-alkyl, —(C6-C12)-cycloalkyl and —(C6-C20)-aryl,
wherein the —(C6-C12)-cycloalkyl radical and the —(C6-C20)-aryl radical may have substituents which are selected from the group consisting off —(C1-C12)-alkyl, —O—(C1-C12)-alkyl and —SO3Na;
and a compound comprising Ru;
c) adding an acid (II) having the formula (IIa) or (IIb):
![]() wherein R4 is —(C1-C18)-alkyl;
![]() wherein R5 is —(C1-C18)-alkyl;
d1) feeding in CO;
e) heating a mixture formed from a) to d1) to convert the ethylenically unsaturated compound directly into an ester or diester of acid (II) without isolation of intermediates.
