摘要：

The strength of intramolecular hydrogen bond of acyl thiourea can be monitored by the hydrogen chemical shift (delta(beta-NH)) We measured the physical properties of 23 N-ferrocenoyl-N'-aromatic (also alkyl, ferrocenyl) thioureas and 14 N-benzoyl-N'-aromatic thioureas including delta(beta-NH), pK(b) in relation with the sigma-parameter of substituents on thearomatic ring. We found that there are a good relationship between the strength of the intramolecular hydrogen bond (delta(beta-NH)) and pK(b) or sigma-parameter of the substituents, thus the substitution effect toword the hydrogen bonding can be revealed.
