    Sila-Riechstoffe und Riechstoffe-Isostere. 11. Mitt. Vergleich von Carbinolen und Silanolen mit Thiocarbinolen und Silanthiolen (1987)

    Notes: Abstract The thiocarbinolsRC(CH3)2SH withR=C6H5CH2 and C6H5CH2CH2 were prepared via reactions 2–5 and compared in their odors (very unpleasant) with the fragrances of the analogous carbinolsRC(CH3)2OH and silanolsRSi(CH3)2OH. Silanethiols, prepared by reactions 6–8, smell less unpleasant than thiocarbinols but decompose easily in the presence of catalytic amounts of ammonium salts (eq. 9). Very pure hexenyl-methyl-vinylsilanethiol (“silathiolinalool”) decomposes contrarily under cyclization to a 1-sila-2-thia-cyclopentane derivative (E 1). The differences of odors, in spite of very similar structures, are discussed in the light of the theory ofAmoore (“Size and structure of molecules rule their odor qualities”).

    Notes: Abstract Sila-analoguesA 2 andB 2 of two drugs from the benzhydryl ether class, chlorphenoxamine and clofenetamine, were synthesized for the first time by the steps shown in scheme 1. They and their precursors I–VI were characterized by their physical (Table 1) and chemical properties and their structures confirmed by n.m.r., mass and infrared spectrocopy (Tables 2–5). Their physiological effects were investigated and compared with those of the carbon analogues (Chapter 5).

    Notes: Abstract The title compoundsR 2Si(NHR 1) (NHR 2) (B) were prepared according to Equ. (2) and (3) and via formerly unknown diphenyl-chloro-organylaminosilanes (A) as intermediates. The complex course of formation ofB in competition withR 2Si (NHR 1)2 (C) andR 2Si(NHR 2)2 (D) (Scheme 1, Equ. (4)–(7), Table 2) was investigated in detail. Results of thermal rearrangement ofB are given in Table 5. Five novelA and six novelB compounds are confirmed by properties, elemental and structural data (Tables 1, 3 and 4).

    Notes: Abstract The formerly unknown Si-dodecamethyl-cyclo-hexasila-3,6,9-triazane (-Sime 2Sime 2NH-)3 (4) was detected in low yield (3–5%) among the reaction products of dichlorotetramethyldisilane and ammonia. The already known main product (50%) Si-octamethyl-cyclo-tetrasila-3,6-diazane (-Sime 2Sime 2NH-)2 (3) reacted after metallation with chloromethylsilanesme n SiCl4−n (n=0−3) to give theN,N′-disubstituted cyclotetrasiladiazanes11–14, from which12 was transformed with ammonia to the correspondingN,N′-bis(aminodimethylsilyl) derivative15, and13 with metallated methylamine to the correspondingN,N′-bis[bis(dimethylamino)methylsily]derivative16. Attempts to construct novel SiN frameworks (g) or (k)-(m) failed.

    Notes: Abstract Preparation of sila-β-ionone (14) was possible by a novel route with yields nearly 5 times higher than before1, with the formerly unknown 1,1,3-trimethyl-1-silacyclohexanone-2 (6) as a key substance. The nine reaction steps may be seen from Scheme 1. 2-Ethinyl-1,1,3-trimethyl-1-silacyclohexan-2-ol (7) could not be dehydrated to give the analogous silacyclohexene derivative9. But dehydration was successful in the case of 2-(1-butin-3-ol) substituents; here only the ring but not the chain hydroxyl group was eliminated.

    Notes: Zusammenfassung Derivatives of benzyldialkylphosphinimides C6H5CH2-PRR′=NH (C) with =NCH3, =NSiMe 3, =O, =S, −CS 2 ⊖ and −NH2]NCS⊖ instead of =NH groups (compare Scheme 1) were prepared and characterized. They neither show the H/D exchange of CH2 benzyl protons with CDCl3 nor the thermal formation of stilbene on heating like the parent compounds C, but they give in the case of =NCH3 and =NSiMe 3 analogously aHorner-Wittig reaction with aldehydes. CS2 reacts with C under NH/S-exchange. The quality of smell ofPhCH2-PRR′ =NCH3 (none, later fishy) is quite different from that of isostericPhCH2-SiRR′ −OCH3 (flowery-honeylike/minty) and the smell of C (metallic/chlorinated hydrocarbon-like) from that ofGrimm hydride isostersPhCH2−PRR′=O (weak; flowery-waxy). The theory ofAmoore (size and shape of molecules control their smell qualities) must be called in question.
