  氯化钛（IV）和季铵盐促进了Baylis-Hillman反应。

  摘要：

  醛与α，β-不饱和酮的Baylis-Hillman反应可受反应温度和路易斯碱的影响很大。当在氯化钛（IV）的存在下，使用催化量的季铵盐（R4N + X-，X = Cl，Br，I）作为Lewis碱在-78摄氏度下进行反应时，氯化羟醛加合物获得1个主要产品。季铵溴化物和碘化物（R4N + X-，X = Br，I）比相应的氯化物（R4N + Cl-）具有更高的催化活性。季铵氟化物（R4N + F-）完全没有活性。路易斯酸和季铵盐的用量会影响反应速率和产物。提出了合理的反应机理。

  [reaction: see text] Highly stereoselective vicinal difuctionalization of alpha,beta-unsaturated ketones for the synthesis of multifunctionalized trisubstituted alkenes is described. The new reaction employs titanium(IV) halides (0.5 equiv) as promoters and inexpensive commercial chemicals as starting materials. The reaction can be performed at room temperature in a convenient vial without the protection

When the reaction was carried out at -78 degrees C using catalytic amounts of quaternary ammonium salts (R4N+X-, X = Cl, Br, I) as Lewis bases, in the presence of titanium(IV) chloride, the chlorinated aldol adduct 1 was obtained as the major product. Quaternary ammonium bromides and iodides (R4N+X-, X = Br, I) have higher catalytic activity

  The Baylis–Hillman reaction can be drastically affected by the reaction temperature and Lewis base. When the reaction was carried out at <−20°C using methyl sulfide as a Lewis base in the presence of titanium(IV) chloride, the chlorinated compound 1 was obtained as the major product. However, if the reaction was carried out at room temperature (10°C) in the presence of titanium(IV) chloride, the elimination

  反应温度和路易斯碱会严重影响Baylis-Hillman反应。当在氯化钛（IV）存在下使用甲基硫作为路易斯碱在＜-20℃下进行反应时，获得了作为主要产物的氯化化合物1。但是，如果反应在室温（10℃）下在氯化钛（IV）的存在下进行，则形成消除化合物3作为主要产物。

  The reactions of aldehydes with 3-buten-2-one (2) were conducted in the presence of (BBr3Me2S)-Me-. or BCl3-Me2S and then worked up with aqueous NaHCO3, affording the a-methylene aldol 3, (alpha -halomethyl aldol 4 or 6, and a-halomethyl enones 5 or 7, respectively. In contrast, the reactions quenched with water gave the alpha -halomethyl enones 5 or 7 in high yields, while the work-up with an aqueous 10% trimethylamine gave the alpha -methylene aldol 3. The phenol 15 and half-acetal 16 were obtained from the reaction of p-nitrobenzaldehyde (1a) with cyclohexenone (10). (C) 2001 Elsevier Science Ltd. All rights reserved.

  Baylis-Hillman reactions of various aryl aldehydes with methyl vinyl ketone at temperatures below -20oC using Lewis acids such as titanium (IV) chloride, boron (III) chloride or zirconium (IV) chloride in the presence of a catalytic amount of selected amines used as a Lewis bases afford the chlorinated compounds 1 as the major product in very high yields. Acrylonitrile can also undergo the same reaction to give
