2,4-(Naphthalene-1,8-diyl)-1,3,2,4-dithiadiphosphetane 2,4-disulfide (1) is very reactive towards nucleophiles, undergoing cleavage of the P-2(mu -S)(2) ring. The reactions of compound I with different bases such as N,N,N ' ,N ' -tetramethyl-guanidine, morpholine, pyrrolidine or NH3 (g) gave the corresponding ammonium salts of 2-5 in nearly quantitative yield. An ammonium salt 6 was obtained when I was reacted with morpholine in the presence of triethylamine. The reaction of 1 with Et3N . 3HF leads to the formation of 7. The new compounds 2-7 formed from the reactions have been studied spectroscopically and for 2, 6 and 7 by X-ray crystallography. (C) 2001 Elsevier Science Ltd. All rights reserved.
