A “sodium trap” based on benzo-15-crown-5 with an exocyclic N-(thiophosphoryl)thiourea moiety

Intramolecular hydrogen bond controlled coordination of N-thiophosphorylated thiourea 2,6-Me2C6H3NHC(S)NHP(S)(OiPr)2 with Ni(II)

“…The parameters of the C@S, C-N, P-N and P@S bonds observed for HL Table 1 Selected bond lengths (Å), and bond angles (°) for HL. ( Table 1) are in the typical range for N-thiophosphorylated thiourea derivatives [7,10,12]. The S(1)-C(1)-N(1)-P(1) backbone in the crystal phase has a E-conformation.…”

Tetraphenylphosphonium salts of N‐thiophosphorylated thiobenzamide, mono‐thioureas or bis‐thioureas

“…These signals are low-field shifted relative to that in the spectra of HL I-V and H 2 L VI,VII [1,5,12,13]. The signal of the phosphorus atom of PPh 4 + in the spectra was found at 22.4-24.1 ppm.…”

“…The crystal structure modification of PhC(S)NHP(S)(O-i-Pr) 2 (HQ) is also reported. were prepared by reaction of the corresponding amine with (i-PrO) 2 P(S)NCS as described previously [5,12,13] I . In the spectra of all obtained salts, there are intense absorption bands of the conjugated SCN group in the area 1520-1564 cm −1 .…”

“…N-Thiophosphorylated thioureas HL I-V were syhthesized as previously described [5,12,13]. Bis-thioureas H 2 L V,VI were syhthesized as previously described [5]. …”

“…At the same time, they form salt-like compounds with alkali or earth alkaline metal cations [1], which might be suitable precursors for transition metal complexes. However, so far only very few of these salt-like compounds have been isolated and characterized, e.g., there is only one crystal structure of a K + salt of a N-(thio)phosphorylthiourea in the literature ([K(Me 2 CO)PhNHC(S)NP(S)(OiPr) 2 ]) [5]. In contrast to this, the structures of some close analogues, salts of N-(thio)phosphorylamides and thioamides, containing the fragment [C(X)NP(Y)R 2 ]…”
