(Received 8 March 2010; accepted 13 April 2010; online 17 April 2010)

There are two independent mol­ecules per asymmetric unit of the title compound, C26H23N2O3PS. Their superposition shows that they differ in the conformation of the CH3CO– group and the benzene rings from the triphenyl­phospho­rane group. In the crystal structure, independent mol­ecules are inter­conected by strong N—H⋯O hydrogen bonds, forming infinite chains along the a axis.

As a part of our ongoing research on the synthetic and structural studies of 1-sulfonyl-1a,2,6,6a-tetrahydro-1H,4H-[1,3]dioxepino[5,6-b]azirine antihyperglycaemics (Dumić et al. 1993 ; 1995, Filić et al. 1996, Vinković et al. 1993, Orešić et al. 2001 and Prugovečki et al.2005 ; 2006), we required suitable synthons carrying 4-acetylaminobenzenesulfanyl and 4-acetylaminobenzenesulfonyl pattern. Thus, the 4-acetylaminobenzenesulfonyimino-triphenylphosphorane (Title compound, I) and bis(4-acetylaminophenyl) disulfide compound (II) were chosen for this study. We prepared both of them in the same reaction, i.e. by treatment of 4-acetylaminobenzenesulfonylazide with triphenylphosphine in acetonitrile at room temperature (Scheme 1). 4-Acetylaminobenzenesulfonyimino-triphenylphosphorane (Title compound, I) was obtained as colorless prisms (m.p. 495-497 K). Bis(4-acetylaminophenyl) disulfide (compound II) was obtained as a yellow solid (m.p. 485-488 K), i.e. in one of its three known forms; m.ps. 488 K, 454-455 K and 395 K respectively (Khmel'nitzkaya, et al. 1934). Its structure and solid state behaviour will be published elsewhere (Žegarac et al. 2010).

In the title compound, C26H23N2O3PS,(I), there are two independent molecules per asymmetric unit. Their superposition shows that they are different in the conformation of the CH3CO group and the benzene rings from the triphenylphosphorane group. In the crystal structure independent molecules are interconected by strong N—H···O hydrogen bonds forming infinite one-dimensional chains along the a axis.

Experimental top

Triphenylphosphine (28.18 g, 0.107 mol) was added in small portions to a stirred solution of 4-acetylaminobenzenesulfonyl azide (13.0 g, 50.4 mmol) [prepared according Ashley et al. (1947)] in acetonitrile (211 ml) at 273 K. After being stirred for 3 hrs at room temperature, the mixture was concentrated under reduced pressure to dryness. The residue was purified by silicagel column chromatography (dichloromethane-methanol-25 % ammonia, 10:1:0.3 v/v) to afford the title compound (I) as a colorless solid [5.9 g, 22.7 %; m.p. 491-495 K; Rf = 0.32 (dichloromethane-methanol- 25 % ammonia, 10:1:0.3 v/v)].

Evaporation of other selected fractions to dryness afford bis(4-acetylaminophenyl) disulfide (II) as a TLC pure yellow solid [5.7 g, 31.5 % m.p. 485-488 K; Rf = 0.26 (dichloromethane-methanol-25 % ammonia, 10:1:0.3 v/v)].

Refinement top

H atoms were positioned geometrically, C-H: 0.93-0.96Å, N-H: 0.86Å, and allowed to ride, with U(H)=1.2/1.5× Ueq(host). In order to avoid beamstop shadowing effects theta(min) was set to 3.24°, with what 20 reflections below this value were left aside the data set.
