A variety of chiral cyanohydrins were readily prepared from aldehydes with TMSCN under the influence of chiral titanium complex formed in situ from $Ti(O^iPr)_4$/TADDOL(I) in the presence of $Ph_3PO$ as additive. The double activation method produces trimethylsilylethers in excellent yield (95%) with moderate enantiomeric excess.

Zirconium(IV) chloride is found to be an efficient catalyst for the electrophilic addition reaction of indole with aldehydes/ketones to afford the corresponding bis(indolyl methanes in good yields. The remarkable features of this new procedure are high conversions, shorter reaction times, cleaner reaction profiles and simple experimental and work-up procedures.

Reductive acetylation of a variety of carbonyl compounds such as aldehydes, ketones and a,b-unsaturated enals/enones was carried out efficiently with pyridine zinc borohydride, (Py)Zn(BH4)2, in a mixture of THF-EtOAc at room temperature or under reflux condition. The corresponding acetates were obtained in high to excellent yields. In addition, chemoselective reductive acetylation of aldehydes over ketones was achieved perfectly with the reagent at room temperature.

Long chain dicationic ammonium salts were used successfully as phase transfer catalyst in the condensation reactions of aromatic aldehydes in water under ultrasonic irradiation for the first time. The quaternary salt having longer distance between the cation centers was more effective than the mono- and dicationic ones having short chain.

Sodium periodate ($NaIO_4$) and potassium iodide (KI) in aqueous ammonia has been used for the one-pot synthesis of nitriles from the corresponding aldehydes and alcohols in moderate to good yield. This transformation, proceeds via an in situ oxidation- imination-aldimine oxidation sequence.

알데히드류는 실내 가정의 건축물 단열재, 실내가구의 칠, 접착제, 하드보드, 악취 제거제, 제지 등 생활 용품에서 공업용품에 이르기까지 광범위하게 사용되며, 그 사용량도 증가되고 있다. 특히, formaldehyde는 urea-와 Phenol-formaldehyde 수지를 합성하는 주요 화합물질이다. 알데히드류 중 포름알데히드는 1ppm 또는 그 이하의 농도로 노출될 경우, 눈, 코, 목의 자극을 유발하고, 농도에 따라서 피부 알레르기, 두통, 메스꺼움, 흥부 압박감, 기관지염, 폐염 및 폐부종을 야기하며, 동물 실험결과, 미국 환경보호처에서는 인체 발암 가능성 물질로 분류하고 있다(US EPA, 1999).

대기 중 formaldehyde는 눈, 코, 목을 자극하고 기관지 천식, 피부 알레르기를 일으킬 뿐만 아니라 동물실험 결과 발암 가능성 물질로 여겨지고 있다(황윤정, 등 1996). 미국 EPA는 formaldehyde를 유력한 인체발암물질(probable human carcinogen, weight of evidence-Group "B1")로 분류하고 있다(IARC, 1982; Edward 등, 1991). (중략)
