Lily.—The lily of the valley—lillium candidim— bears flowers which emit a peculiar and powerful fragrance. This aroma may be extracted by the process of enfleurage but eight or ten repetitions, with t je same fat or bearsoil and fresh leaves, are required to obtain the requisite strength. 

Increased heart rate, restlessness, convulsions, and stupor were observed in a 2-year-old that had been mistakenly administered a teaspoon full of lily-of-the-valley fluid extract (Andrew 1898).

Geraniol, as Its name Implies, occurs in oil of geranium but also constitutes about 50% of rose oil, the extract of rose petals. Farnesol, which occurs In the essential oils of rose and cyclamen, has a pleasing lily-of-the-valley odor. Both geraniol and farnesol are used in making perfumes. 

BASF patented the hydroformylation of 2,6-dimethylhept-l-en-6-ol, obtainable from the corresponding ketone via Grignard reaction (Scheme 6.41) [133]. The reaction with syngas was performed in the 1 kg scale with an unmodified Rh catalyst to afford 3,7-dimethyloctan-l-al-7-ol (hydroxycitronellal) in 90% yield. The use of a PPhg-modified catalyst did not improve this result. Usually, hydroxycitronellal is extracted from ethereal oils or can be alternatively produced by the hydration of citronellal bisulfite in an acidic medium [134]. The annual production is about 11001 [135]. The oil has a sweet floral scent, which is reminiscent of lilac, lily, lily of the valley, or lime. By the same protocol, also related hydroxy aldehydes with other interesting olfactory properties become accessible.
