Claim 0:
1. A method of preparing compounds of formula (I), comprising reacting compound of Formula II with an organic compound of Formula (V), (VI), (VIII) or (IX), where:
independently from one another, R0, R1, and R2 are chosen from the group consisting of an alkoxy group, an aryloxy group, an alkyl group, a carboxyl group, an aryl group, and a siloxy group, said alkyl, aryl, alkoxy, aryloxy or siloxy groups optionally being substituted,
n=0 or 1;
m=1;
when n=0 and m=1, Z is —NR3R4 where:
independently from each other, R3 and R4 are chosen from the group consisting of a hydrogen atom, an alkyl group, said alkyl group optionally being substituted; or
taken together with the nitrogen atom to which they are bonded, R3 and R4 form an optionally substituted heterocycle;

when n=m=1,
independently from one another, R3, R4 and R5 are chosen from the group consisting of a hydrogen atom, an alkyl group, a halogenoalkyl group, an alkenyl group, a cyclic alkenyl group, an aryl group, a heteroaryl group, and a heterocyclic group, said alkyl, alkenyl, aryl, heteroaryl, or heterocyclic groups optionally being substituted; or
together with the carbon atom to which they are bonded, R3, R4 and R5 form an optionally substituted aryl; or
together with the carbon atom to which they are bonded, R3 and R4 form an optionally substituted cyclic alkyl and R5 is as defined above; or
together with the carbon atom to which they are bonded, R3 and R4 form an optionally substituted cyclic alkenyl and R5 is as defined above; or
together with the carbon atom to which they are bonded, R3, R4 and R5 form a cyclic alkenyl; and
Z is chosen from the group consisting of:
X or Y as defined below;

characterised in that a silylated formiate of formula (II), where R0, R1 and R2 are as defined above;, where:
R3, R4, and R5 are as defined above;
R8 is chosen from the group consisting of a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a heteroaryl group, and a heterocyclic group, said alkyl, alkenyl, alkynyl, aryl, heteroaryl, or heterocyclic groups optionally being substituted;
X is an oxygen atom; and

Y is chosen from a group consisting of an oxygen atom or a sulphur atom;

in the presence of a catalyst and optionally of an additive.
