We have redetermined the known structures of (i) methylthiourea (MTU) and (ii) 1,1-dimethylthiourea (1,1-DMTU), and investigated the structure of 1,3-dimethylthiourea (1,3-DMTU), which was however severely disordered. We report the structures of crystalline adducts of (iii) MTU with morpholine (1:1), (iv)

There is evidence that chronic exposure to high levels of ambient particulate pollutants (PM) is associated with chronic airflow obstruction, but how this occurs is not known. We exposed rat tracheal explants to Ottawa urban air particles (ECH93) or diesel

A Pauson-Khand type of conversion of enynes to bicyclic cyclopentenones employing the commercially available Co2(CO)8 and tetramethylthiourea (TMTU) as catalysts is described. This method allows a variety of enynes with diverse functional groups to be cyclized into cyclopentenones of interest.
