Reaction of benzyl azide (15a) with the sterically hindered C=S group of 4,4-dimethyl-1,3-thiazole-5(4H)-thiones 14 (Scheme 3) and 1,1,3,3-tetramethylindane-2-thione (17, Scheme 4) at 80 deg C leads to the corresponding imines in high yield, without forma
SELONES AS INTERMEDIATES IN THE PREPARATION OF EXTREMELY STERICALLY HINDERED MOLECULES
Guziec, Frank S.,Sanfilippo, Lynn James,Murphy, Christopher J.,Moustakis, Christine A.,Cullen, Edward R.
, p. 4843 - 4852 (2007/10/02)
The preparation and reactions of selones, selenium analogues of ketones, are described with particular emphasis on their utility in the preparation of extremely sterically hindered molecules.Mechanistic questions related to these reactions are discussed and evidence for "active selenium" is presented.Selenophilic additions of organometallic compounds to selones are also reported.
Twofold Extrusion Reactions of Selones and Azides: the Preparation of Very Sterically Hindered Imines
Guziec, Frank S.,Moustakis, Christine A.
, p. 63 - 64 (2007/10/02)
The twofold extrusion reaction of a selone with an aromatic azide is a useful method for the preparation of sterically hindered imines.
