- the Wittig reaction is an important reaction in organic synthesis.
- Organocatalytic reactions are of considerable interest in chemical processes [10]. Relative to the metal -based catalysts, organocatalysts avoid the use of metals which, in many instances, may be expensive, corrosive or toxic. Furthermore, organocatalysts can be chemically altered to confer unique properties such as reaction selectivity. While most metal catalysts function as Lewis acids, organocatalysts tend to function as either Lewis bases [11] or as Br ⁇ nsted acids [12]. Metal-free Lewis acid organocatalysts are relatively rare and most of them are silicon based [13].

Reaction of 2 with benzyl tosylate yielded the zwitterionic phosphonium salt 3a together with l,2-dimethyl-3- butylimidazolium tosylate.
- the zwitterionic phosphonium salt 3a can be prepared from the reaction of 1 with benzyl bromide (Scheme 1).
- Zwitterionic phosphonium sulfonate salts 3b-d were prepared similarly from the corresponding bromides.
- Table 1 Wittig Reaction of 3a with various aldehydes.
- ketones such as benzophenone, acetophenone, cyclohexanone and acetone, were found to be unreactive under the reaction conditions and were quantitatively recovered.
- 4-Acetylbenzaldehyde (4i) reacted chemoselectively with 3c to provide compound 5q in substantially quantitative yield.
- Separation of the product alkene from the reaction mixture could again be conveniently achieved by the addition of a less polar solvent, a non-limiting example of which includes diethyl ether, to allow precipitation of the phosphine oxide by-product 6.
- the zwitterionic phosphonium salt 3c is generated in situ.
- This "one-pot" reaction provides a more convenient alternative over the Homer- Wadsworth-Emmons (HWE) modification [17] to effect the olefmation of aldehydes.
- HWE Homer- Wadsworth-Emmons
- the HWE reaction remains the more stereoselective alternative, affording the thermodynamically more stable (£)- ⁇ , ⁇ -unsaturated esters.
- the mixture of stereoisomers obtained using the zwitterionic phosphonium sulfonates of the present invention can be conveniently isomerized to the thermodynamically more stable E-isomer [18].
- the reaction side-product phosphine oxide 6 was precipitated and removed by filtration.
- the crude reaction product was subsequently dissolved THF followed by the addition of 25 mol% diphenyl disulfide. After overnight refluxing, pure ESl was obtained.
- TPPMSO was conveniently reconverted into TPPMS using
- Acetalization reactions are typically affected and catalyzed using
- Br ⁇ nsted acids such as HCl and PTSA
- metal-based Lewis acid such as TiCl 4 , ZrCl 4 , Sc(OTf) 3 , LaCl 3 , CeCl 3 , InCl 3 , RuCl 3 , Bi(OTf) 3 and MeReO 3
- silicon-based Lewis acids such as TMSCl, TMSOTf and TMSOFs [20].
- a zwitterionic phosphonium sulfonate salt (9g and 9h) which constitutes a useful reagent for the preparation of acetals from the corresponding aldehydes.
- suitable electron withdrawing groups comprise CF 3 , CCl 3 , CBr 3 and CI 3 .
- triphenylphosphine-OT-sulfonate (1) facilitates the activation of the aldehyde (Lewis base) by the sulfonate salt.
- a series of phosphonium salts 9 were prepared and tested for their efficiency for the catalytic acetalization of /7-nitrobenzaldehyde (10a) and the results summarized in Table 3. The catalytic acetalization reactions were performed in methanol at 25 0 C over a period of 12 hours using 5 mol% of the phosphonium sulfonate salt (Scheme 4).
- phosphonium salts 9a and 9b did not provide any of the desired acetal product.
- phosphonium salt 9c bearing an electron- withdrawing ester moiety, afforded the acetal product 11a in good yield (87%).
- Phosphonium salt 9d comprising the more electron-withdrawing CBr 3 group, afforded the acetal product in slightly improved yield (90%).
- the introduction of an electron withdrawing group in the form of a sulfonate on one of the phenyl rings did not improve the reactivity of the phosphonium salts as no reaction could be observed for compounds 9e and 9f.
- Compound 9g was only poorly soluble in methanol and only 15% of the desired acetal product was observed after 12 hours.
- Table 3 Catalytic acetalization of />-nitrobenzaldehyde using zwitterionic phosphonium salts 9.
- the phosphonium sulfonate salt 9h effectively catalyzed the acetalization of both aromatic and aliphatic aldehydes using methanol.
- the phosphonium sulfonate salt 9h provided superior results over phosphonium salt 9d (comparison of entries 2, 5 and 9 with entries 1, 4 and 8 respectively) which appears indicative of an additional effect imparted by the sulfonate group.
- the lower yield (entry 8) obtained with 9h was likely due to the equilibrium being adversely affected by the methoxy substituent. Indeed, by adding a dehydrating agent (e.g. MgSO 4 ) to the reaction mixture, a substantially higher yield (77 %) of the acetal product could be obtained.
- a dehydrating agent e.g. MgSO 4
- Table 4 Catalytic acetalization of various aldehydes using zwitterionic phosphonium sulfonate 9h.
- Zwitterionic phosphonium sulfonate 9h also effected the acetalization of j ⁇ -nitrobenzaldehyde using a variety of alcohols as summarized hereinbelow in Table 5. In the case of higher boiling alcohols, a stoichiometric amount of the alcohol was used and the acetalization reaction was carried out in CH 2 Cl 2 as the solvent.
- the catalyst is soluble in relatively polar organic solvents such as methanol and can thus be readily and quantitatively recovered from the reaction mixture by the addition of a non-polar organic solvent such as ether. Therefore, as was previously observed for the formation of alkenes, the separation and recovery of 9h from the reaction mixture was effectively carried out by precipitation using a non-polar solvent (e.g. ether) following completion of the reaction. Finally, recovered 9h can be reused without loss of catalytic activity. In fact, using the acetalization of />-nitrobenzaldehyde with methanol as a model system, 9h was used in seven cycles of acetalization without diminished yield.
- a non-polar solvent e.g. ether

- TPPMSO (6) 1 U NMR (400 MHz, CDCl 3 ): ⁇ 8.13- 8.07 (m, 2H), 7.81- 7.75 (m, IH), 7.69- 7.62 (m, 7H), 7.58- 7.53 (m, 4H); 31 P NMR (81 MHz, DMSO- d 6 ): 32.6 (s).
- Phosphonium salt 9h (5 mol%) and 4-nitrobenzaldehyde 4a (0.2 mmol) were dissolved in MeOH (1 mL) and stirred at room temperature overnight. Ether (3 mL) was subsequently added and the reaction mixture filtered. The recovered phosphonium salt 9h was redissolved in MeOH and reacted with further 4- nitrobenzaldehyde 4a. A total of seven (7) reaction cycles were performed, the yields of acetal product being respectively 99%, 98%, 96%, 97%, 96%, 97% and 97%.
