Phosphorus-nitrogen compounds: part 30. Syntheses and structural investigations, antimicrobial and cytotoxic activities and DNA interactions of vanillinato-substituted NN or NO spirocyclic monoferrocenyl cyclotriphosphazenes

Ali Osman SOLAK

The gradual Cl replacement reactions of NN (1–3) or NO spirocyclic monoferrocenyl cyclotriphosphazenes (4 and 5) with the potassium salt of 4-hydroxy-3-methoxybenzaldehyde (potassium vanillinate) resulted in the mono (1a–5a), geminal (gem-1b–5b), non-geminal (cis-5b and trans -1b–4b), tri (1c, 3c–5c) and tetra-vanillinato-substituted phosphazenes (1d–5d). All the phosphazene derivatives have stereogenic P-center(s), except tetra-substituted ones. The vanillinatophosphazenes have reversible voltammograms with one-electron anodic and cathodic peaks which are attributed to ferrocenyl redox probe. ...More

Flora and Plant Formations Distributed in At-Bashy Valleys–Internal Tien Shan in Kyrgyzstan and Interactions with Climate

Nazgül İMANBERDİYEVA

In this chapter, the flora and vegetation of Kyrgyzstan’s At-Bashy valley and inner Tien Shan, together with the vegetational changes due to climatic impacts, are presented. The data presented covers the period between 2000 and 2014. More than 50 % of the higher plants in Kyrgyzstan grow on a very small territory. There are more than 4100 species distributed in the country and 1600 of these possess economic and practical value. Flora in At-Bashy valleys is represented by 222 species of higher plants belonging to 130 genera and 35 families. Steppes are a dominant vegetation type in the study ar ...More

Soil–Plant Interactions in the High-Altitude Ecosystems: A Case Study from Kaz Dağı (Mount Ida), Turkey

Zeki SEVEROĞLU

Kaz Dağı, the ancient Mount Ida, is a mountainous area and one of the important biodiversity spots, located in the north of Edremit in northwestern Anatolia. The area abounds in fertile soils, wetlands, underground resources, favorable climatic conditions, interesting geomorphological characteristics, and several world famous archeological and cultural places. Southwestern part of the mountain has been declared as a national park in 1993, which hosts a very rich and diverse flora including many endemic and rare species; a majority of these are of great economical and ethnobotanical significanc ...More
