It is marketed as a 35-40 per cent, solution in water (formalin). The rpactions of formaldehyde are partly typical of aldehydes and partly peculiar to itself. By evaporating an aqueous solution paraformaldehyde or paraform (CHjO), an amorphous white solid is produced it is insoluble in most solvents. When formaldehyde is distilled from a 60 per cent, solution containing 2 per cent, of sulphuric acid, it pol5unerises to a crystalline trimeride, trioxane, which can be extracted with methylene chloride this is crystalline (m.p. 62°, b.p. 115°), readily soluble in water, alcohol and ether, and devoid of aldehydic properties ...

The synthetic applications of o-halobenzyl sulfones as precursors of 1,3- and 1,5-zwitter ionic synthons, have been investigated and their sulfonyl carbanions, generated by means of the phosphazene base Et-P2 reacted with different electrophiles, such as alkyl halides and aldehydes. When the alkylation was performed with ethyl bromoacetate, orf/io-substituted cinnamates were obtained after a subsequent p-elimination of sulfmic acid. When the aldol reaction was performed with paraform aldehyde, vinyl sulfones were obtained. The...

Trimethylchlorosilane, dimethyldisulfide, butyl bromide, butyl iodide, paraform, acetic and pivalic aldehydes, benzaldehyde, acetone, and cyclohexanone are used as electrophilic reagents relative to N-allenylpyrrole metalated with butyUithium. The conditions of the second stage of the reaction, electrophilic substitution, or addition (for aldehydes and ketones) depend upon the electrophile anployed. In all the cases, a-allenic derivatives are formed as a rule (Table 2.20). 

However, the reaction with aldehydes and ketones affords, along with allenic alcohols, their N-ethynyl isomers, the content of which in the products mixture can reach 60% (in the case of the reaction with paraform) (Scheme 2.224). The mixture composition is defined to a large extent by the reaction conditions and the electrophile nature.
