Study of I-Strain Relief in the Intermediate When Forming Spiro Ketones from Unsymmetrical Cycloalkylidenecycloalkanes, Their Dibromides, and Their Pinacols
摘要:
Three unsymmetrical intercyclic olefins, their dibromides, and their pinacols were prepared, each so the two carbons involved at the functional group were part of a different sized ring. The pinacols were reacted with 25% sulfuric acid and with boron trifluoride etherate, the dibromides with silver nitrate,and the olefins with mercuric acetate and with trifluoroperacetic acid. The predominant spiro ketone found in each product mixture was used to determine which carbon, and hence which size ring, could better undergo the sp(3) to sp(2) or the sp(2) to sp(3) transition. The findings were consistent with Brown's observations on ring strain.

Compounds of the substituted pyrazole class of Formula (I) as treatments for cancer are reported. A method of treating cancer in which a compound that inhibits the activity of receptor kinases is described. Said method is effective and can be provided in addition to standard therapies, notably chemotherapy using cytotoxic drugs and other forms of immune therapy including therapeutic vaccines.
The present invention relates to catalytic compositions for esterification, transestrification and polycondensation reactions, a process for the catalysis of said reactions employing such catalytic compositions and polyesters for resins obtainable by this process.
