Tetraalkylammonium salts bearing PF6- and BF 4- anions have been recognized as recoverable phase-transfer catalysts for the synthesis of 1,1-dichlorocyclopropane and α-(trichloromethyl) carbinol derivatives from alkenes or aldehydes in the heterogeneous system KOH(s)/CHCl3. The catalysts retained their catalytic activity over several reaction cycles. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

2,4-Diamino-6(3,3,3-tribromo-1-propyl)-1,3,5-triazine and 2,4-diamino-6(3,3,3-trichloro-1-propyl)-1,3,5-triazine were prepared by the reaction of the corresponding methyl or ethyl γ-tribromo-butyrate or methyl or ethyl γ-trichlorobutyrate with biguanide. The N-methylol derivatives of the diaminotrihalopropyl triazines were prepared by the reaction of the triazines with aqueous formaldehyde. Two pure tetramethylol derivatives were prepared, namely: 2,4-bis[bis(hydroxymethyl)amino]-6-(3,3,3-tribromo-1-propyl)-1,3,5-triazine and 2,4-bis[bis(hydroxymethyl)amino]-6-(3,3,3-trichloro-1-propyl)-1,3,5-triazine. The tetramethylol derivatives were used to impart durable flame retardancy and wrinkle recovery to cellulosic textiles, particularly to cotton. Flame-retardancy was also imparted to wool and to blends of cotton and polyester.
