New tert. amino gp. contg. siloxane derivs. of di:cyclopentadiene - allows wider choice of spacer gps. leading to a range of prod. properties

摘要

Tert. amino gp. contg. siloxane derivs. of dicyclopentadiene of general formula (I) are new. In (I) Y = lower alkyl residue or phenyl residue Z = Y or (Y)3SiO- m = 0-49 n = 1-50 m:n = 0-10 A = -O- or -OOC- R1 = -(CH2(r-, -(CH2CH2O)r-(CH2)r-, -(CH2CH2CH2O)r-(CH2)r-, -CH2CH(OH)-CH2- or -(CH2)r-OOC-CH2- with r = 1-10; B = gp. (i)-(ii) R2, R3 = 1-4C alkyl, hydroxyalkyl. More specifically, Y = pref -CH3 m = 0-19, pref. 0-5 n = 1-20, pref. 1-8 m:n = 0-5, pref. 0-2 and r = 1-5, pref. 1-2. USE/ADVANTAGE - (I) permits wider choice of spacer gps. leading to range of prod. properties, e.g. surfactants for different solvents. In an example, 2(3)-heptamethyltrisiloxanyl -5(6)-chloroacetyl-2,3,3a,4,5,6,7,7a- octahydro-r,7-methano-1H-indene (9g, 0.02 mol) and morpholine (8g, 0.092 mol) were warmed together to 403K within 3 minutes, whereupon a white salt pptd. out. After 1.5 hours the reaction mixt. was cooled to room temp. and mixed with pentane (20 ml) and 10% aq. NaOH soln. (10 ml). The pptd. salt went into soln. in the aq. phase. The tert amine contg. pentane phase was sepd. off and washed 5 times with water (50 ml). Removal of the solvent left a light yellow oil (9.1g) that was shown by G.C. analysis to be completely converted to a morpholine deriv. of formula (II).
