Claim:
A process of forming a compound of general formula (33) wherein R 1 and R 2 are independently from one another one of a silyl group, an aliphatic group and an alicyclic group with a main chain having 1 to 20 carbon atoms and 0 to 7 heteroatoms selected from the group consisting of N, O, S, Se and Si, R 3 is one of H, a silyl group, an aliphatic group, an alicyclic group, an aromatic group, an arylaliphatic group and an arylalicyclic group with a main chain having 1 to 20 carbon atoms and 0 to 7 heteroatoms selected from the group consisting of N, O, S, Se and Si, and R 4 is one of (i) the group —CH═CH—R 9 , wherein R 9 is one of H, a silyl group, an aliphatic group, an alicyclic group, an aromatic group, an arylaliphatic group and an arylalicyclic group with a main chain having 1 to 20 carbon atoms and 0 to 7 heteroatoms selected from the group consisting of N, O, S, Se and Si, (ii) an aromatic group, (iii) an arylaliphatic group and (iv) an arylalicyclic group, the aromatic, arylaliphatic or arylalicyclic group comprising a main chain having 1 to 20 carbon atoms and 0 to 7 heteroatoms selected from the group consisting of N, O, S, Se and Si, R 11 is one of (i) H, (ii) a silyl group, (iii) an aliphatic group, (iv) an alicyclic group, (v) an aromatic group, (vi) an arylaliphatic group, (vii) an arylalicyclic, the aliphatic, alicyclic, aromatic, arylaliphatic or arylalicyclic group comprising a main chain having 1 to 20 carbon atoms and 0 to 7 heteroatoms selected from the group consisting of N, O, S, Se and Si, (viii) a carbonate group —O—C(O)—O—R 17 , and (ix) a carbamoyl group —O—C(O)—N(R 17 )—R 18 , wherein R 17 and R 18 are independent from one another H or one of an aliphatic, an alicyclic, an aromatic, an arylaliphatic, and an arylalicyclic group with a main chain of a length of 1 to 20 carbon atoms, comprising 0 to 6 heteroatoms selected from the group consisting of N, O, S, Se and Si, the process comprising: providing a first compound of the general formula (1), providing a second compound of the general formula (2) contacting the first compound of formula (1) and the second compound of formula (2) in the presence of a compound of general formula (X), wherein R 6 is one of H, OMe, OH, OTf, SH, and NH 2 , R 7 is one of OH and —N(R 8 )H, wherein R 8 is one of H, a carbamoyl group, and a thiocarbamoyl group and represents one of a single and a double bond, and allowing the first and the second compound to undergo a reaction for a sufficient period of time to allow the formation of a compound of general formula (23)
