Organotin Pseudohalides Containing Tin-Oxygen Bonds

Organotin pseudohalides containing tin-oxygen bonds are only quite recently known. Several of the new derivatives may contain a four-membered stannoxane -ring, cf. the structural formula in the Main Volume, page 33 The following scheme gives synthetic methods for the compounds summarized in Tables l60 and l6l. 

R = organic group R = H, R X = halogen X pseudohalogen, x heteroatomic group like OR, OH, functionally substituted alkoxy group.
