A NOVEL FORMATION OF 1,2,3-BUTATRIENE EPISULFIDES BY THIONATION OF METHYLENECYCLOPROPANONES

Sterically hindered methylenecyclopropanones were thionated with phosphorus pentasulfide in pyridine to afford novel 1,2,3-butatriene episulfides and thiiranoradialene derivative via methylenecyclopropanethione intermediate.

OXIDATION OF 1,2,3-BUTATRIENES: A FACILE FORMATION OF METHYLENECYCLOPROPANONES AND THEIR SUBSEQUENT PHOTODECARBOXYLATION

A peracid oxidation of some sterically hindered 1,2,3-butatrienes (4) using an alkaline biphasic solvent system was examined, and the resulted methylenecyclopropanones (5) were readily photodecarboxylated to give the corresponding allenes (6) in good yiel

Synthesis, Crystal and Molecular Structure of 1,1,3,3-Bis(1',1',5',5'-tetramethylpentamethylene)allene

The symmetrically substituted allene derivative 1,1,3,3-bis(1',1',5',5'-tetramethylpentamethylene)allene (4) crystallizes in the monoclinic space group P21/c with Z = 4 molecules in the unit cell.The deviation of 2.4 deg from the linear arrange
