Search for strong guanidine bases. Theory and experiment in concert

Tayloring and preparation of strong neutral organic bases has been subject matter of considerable interest in recent years. This is not surprising since strong neutral organic bases have some important advantages over their ionic counterparts. They require milder reaction conditions and enable reactions to be carried out in homogeneous environment. In this talk recent efforts in developing new highly basic guanidine derivatives aiming at developing potent basic catalysts will be addressed. Special attention will be put on an emphasis on guanidines substituted with heteroatomalkyl chains. Starting with previously studied dimethylpropyl and methoxypropyl substituted guanidines, we shall move to in silico design and basicity study of guanidine derivatives carrying different heteroatom centers at the termini of the alkyl chains attached to the parent guanidine. In the last part of the talk in silico design and basicity of higher guanidine analogons (biguanides, triguanides and tetraguanides) will be presented.
