Silylation of substitued dioles by means of hexamethyldisilazane leads to 2,2,7,7-tetramethyl-3,6-dioxa-2,7-disilaoctane derivatives. Reactiions of these dioles with hexamethylcyclotrisilazane afford substituted 1,3-dioxa-2-silacyclopentanes.

Silylation of the diols I–V with hexamethylcyclotrisilazane (VI) leads to the 3,3-dimenthyl derivatives of hydrogenated 2,4-dioxa-cis- (VII) and -trans-benzo- (VIII), -cyclohexeno- (IX), -cyclohexadieno- (X) and -naphtho-3-silepines (XI). The diols

Male adult Wistar rats were treated for 8 weeks with an organosilicone [2,2-dimethyl-4-(chloromethyl)-1,3-dioxa-2-silacyclopentane] employing two different dosages (25 and 50 mg/kg body weight i.p. daily) and the changes in the tubular apparatus of t

In our previous papers (Haider et al. 1983, 1984), we reported the gross effects of SOC (2,2-dimethyl-4-(chloromethyl)-1,3-dioxa-2-silacyclopentane) as detectable after a 3-week-application period, specifically the effects of SOC on rat testis and sp

Summary The effects of an organosilicon compound SOC, a derivative of 1,3-dioxa-2-sila-cyclopentane, on rat spermiogenesis were studied with the help of histochemical and enzyme histochemical methods. The rats were injected with SOC i.p. daily for 3
