Process for preparing an acetal from an olefin using an iodine-alkyl compound

Process comprising the process steps of:

• a) initially charging an olefin;
• b) adding a compound of formula (I):
• where R1, R2, R3, R4, R5, R6, R7, R8 are selected from:
• —H, —(C1-C12)-alkyl, —(C6-C20)-aryl;
• and, if R1, R2, R3, R4, R5, R6, R7, R8 are —(C6-C20)-aryl, the aryl ring may have substituents selected from:
• —(C1-C12)-alkyl, —O—(C1-C12)-alkyl;
• c) adding a Pt compound selected from:
• Pt(II)(COD)Me2, diphenyl(1,5-COD)Pt(II), Pt(II)(acac)2, Pt(0)(PPh3)4, Pt(0)(DVTS) solution (CAS:
• 68478-92-2), Pt(0)(ethylene)(PPh3)2, tris(benzylideneacetone)Pt(0), Pt(II)(OAC)2 solution, Pt(0)(t-Bu)2, Pt(II)(hexafluoroacetylacetonate)2;
• d) adding an iodine-alkyl compound;
• e) adding an alcohol selected from:
• methanol, ethanol, 1-propanol, 1-butanol, 1-pentanol, 1-hexanol, 1-heptanol, 1-octanol, ethane-1,2-diol, propane-1,2-diol, propane-1,3-diol, butane-1,4-diol;
• f) feeding in CO and H2;
• g) heating the reaction mixture from steps a) to f), to convert the olefin to an acetal.
