✦ Synopsis

1,

2,
fide 1 reacts with substituted 2-amino-1,4-naphthoquinons 2a-d to give 4,5,4Ј,5Ј-benzodiphenoquinonebis-1,3,2-thiazaphospholine-2-sulfide derivatives of type 3. Compatible analytical and spectroscopic results were obtained for all the new compounds. A mechanism is proposed to explain the formation of compounds 3.
